Re: [GENERAL] FATAL: the database system is starting up
fluxh wrote I have the same problem. I have a log like patrick keshishian. I have not a backup. I don't know that do. Help me please!!! Information: - Server with RAID1 on SAS HD Hot-plug. - Ubuntu Server 12.04 x64. - Postgresql 9.1. When I do psql PostgreSQL shows psql: FATAL: the database system is starting up and when I write pg_dump or I try connect with pgAdmin3. You should supply your actual log file and also provide some narrative of what exactly you were doing prior to this condition occurring. Some context as to architecture wouldn't hurt - such as how many and what kinds of applications are connecting to the database, especially those that maintain persistent connections. System commad output like top and ps may also be of value though after you provide the background a more directed QA can follow. In short it sounds like you need to force PostgreSQL to shutdown and then start it back up again. If you are using the apt package you'd do this via some invocation of pg_ctlcluster for which there is ample documentation of both it and the underlying pg_ctl command.

[GENERAL] UNIQUE contraint that is initially deferred in Postgres 8.4.13
Hi list, I'm having trouble with a UNIQUE constraint that I need to have DEFERRABLE INITIALLY DEFERRED. On my Dev machine (Postgres 9.1) it works fine: alter table foo drop constraint bar; ALTER TABLE alter table foo add constraint bar UNIQUE (col1, col2) deferrable initially deferred; ALTER TABLE In Production (Postgres 8.4.13) this blows up in my face although it should be supported according to the docs: alter table foo drop constraint bar; ALTER TABLE alter table foo add constraint bar UNIQUE (col1, col2) deferrable initially deferred; FEHLER: Syntaxfehler bei »DEFERRABLE« LINE 1: bar UNIQUE (col1, col2) DEFERRABLE... ^ (i.e. syntax error at DEFERRABLE, psql seems to ignore my locale setting). Does somebody know what the reason for this could be? I'm kind of puzzled.

[GENERAL] puzzling perl DBI vs psql problem
I have a weird issue that I can't figure out. If I run the exact same query through psql as through perl DBI, I get different results. I get far fewer results with DBI than through the psql command line. Any ideas why that would be? The query is: SELECT st.description, st.scene_thing_instance_id, st.scene_id, sc.description, st.scene_thing_id, s.description, st.position_x, st.position_y, st.position_z, CASE when (st.description = 'absolute root'::text) then 1 when (st.description ilike 'root%') then 2 else 3 END as s1, s.shape_name_id, sn.shape_name from scene_thing_instances st left join scene_things s on st.scene_thing_id = s.scene_thing_id left join scenes sc on st.scene_id = sc.scene_id left outer join shape_names sn on s.shape_name_id = sn.shape_name_id order by s1, st.description I get 14 rows back via psql, but I only get 5 rows back via DBI. It's very puzzling. I copied and pasted the query from the program's log file, so I know I'm doing the exact same query. If it matters, I'm only seeing the rows with 'root' in them via DBI, which the CASE statement refers to. Thanks, Susan

Re: [GENERAL] puzzling perl DBI vs psql problem
Yes, I am running with use strict. The statement I pasted in is after perl quoting, being written out by the same perl program. I just take that statement and paste it into the psql window. DBI-trace showed nothing out of the ordinary. It just shows the lines being fetched that I am seeing in the web program, not the lines I get from psql. Another odd thing is that it is apparently not logging statements from Perl, only from psql. I don't know why. I thought I had it set up right to log to syslog. I've had good luck before with that on other installations. Here are the log settings in postgresql.conf: log_destination = 'syslog' # Valid values are combinations of # stderr, csvlog, syslog, and eventlog, # depending on platform. csvlog # requires logging_collector to be on. # This is used when logging to stderr: logging_collector = on # Enable capturing of stderr and csvlog #logging_collector = off# Enable capturing of stderr and csvlog # into log files.

Re: [GENERAL] puzzling perl DBI vs psql problem
No, I am connecting to the right database, as my log info shows. No duplicate table names, except in different databases. Those tables show all the data I expect, oddly enough, if I connect the perl program to that database. It is only this database that is giving me trouble. Which is another oddity. The identical test database is working fine. Only this database is giving me trouble. Naturally the live database is causing problems.

The statement I pasted in is after perl quoting, being written out by the same perl program. I just take that statement and paste it into the psql window. DBI-trace showed nothing out of the ordinary. It just shows the lines being fetched that I am seeing in the web program, not the lines I get from psql. Another odd thing is that it is apparently not logging statements from Perl, only from psql. I don't know why. I thought I had it set up right to log to syslog. I've had good luck before with that on other installations. That’s supports Tom’s theory that you’re not connecting to the database you think you are. There’s no difference from the database’s PoV between queries from psql and perl. Conceivably connecting as different users could change the result too, though it seems unlikely here. Here are the log settings in postgresql.conf: [fairly normal settings deleted] Could it have something to do with permissions on /var/log/postgresql? It is writeable by root only. The perl program runs under apache. No, that file is written by syslog, nothing to do with the client. If the perl is running under apache, though, is it possible that it’s a long-running process that’s kept a transaction open and is seeing old data? Bounce apache and see if anything changes.

No, I don't have 2 instances running. I default the port on the psql command line, and the perl program is using 5432, as normal. Now, I'm discovering that syslog is no longer logging anything. I bounced it, but to no avail.

Re: [GENERAL] puzzling perl DBI vs psql problem
1) Run both psql and perl under strace and search the output for which sockets it connects to. eg, strace -o /tmp/psql.log psql -Upgsql -dmydatabase -cselect version(); 2) Add a query into your perl script to perform the following SQL and print the results: select current_database(); select current_schema(); select inet_server_addr(); select current_user; (and others, see http://www.postgresql.org/docs/9.3/static/functions-info.html for more functions) Do the same from your psql. Compare the output. Are you 110% sure that you are connecting to the same database, as the same user, and using the same schema?

Re: [GENERAL] puzzling perl DBI vs psql problem
I finally figured it out, after changing my code to output the lines per the number of rows of output, instead of until data[0] was blank. It turned out that data[0] was sometimes blank, and I forgot about that, and was stopping the output after I got back an empty record (or so I thought). So, all my fault. The syslog thing I fixed by changing log_min_duration to 0, instead of letting it default. I don't think this used to be the default (to not log any statements). Thanks for all the ideas, anyway, folks.
