Re: [GENERAL] Multiple postgresql installations on one machine.
Charles Tassell [EMAIL PROTECTED] writes: I may be wrong, but I don't think it's possible to have them on the same port. The problem is that the TCP/IP port defaults to the same as the UNIX sockets port, and UNIX sockets are local to the machine, so they are completely independent of IP addresses and can not be duplicated. Unix sockets need to have unique pathnames in the local filesystem. The PG port number is actually only a component of the file name. So all you need to do if you need to have conflicting port numbers is to vary the unix_socket_directory parameter for each postmaster. However, varying the port number is probably a simpler attack... I can't seem to tell psql where to find the moved unix socket. Use -h /path/to/directory/containing/socket. AFAIR you can set the path in PGHOST environment variable, if that helps. regards, tom lane ---(end of broadcast)--- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly

Re: [GENERAL] Rotating PostgreSQL LOGs on Web site ??
I think the general solution is to compile with syslog support and use the normal syslog rotation scripts. Hi, I'm interesting to know how to find a solution for rotating the PostgreSQL log file ... I'm usgin thoses options for the log generated : silent_mode = false log_connections = false log_timestamp = true log_pid = false debug_level = 2 # range 0-16 debug_print_query = false debug_print_parse = false debug_print_rewritten = false debug_print_plan = false debug_pretty_print = false BUT I have in 13 days a log file of 12 Gb ... The big trouble is ... that is a web site Database ... So It's IMPOSSIBLE for me to STOP the database ... or finding a solution to not loose my members subscribing ... And if I stop PostgreSQL ... I'll have also to restart the Apache servers wich are connected to the database ... and that's mean really good cron timing ... So if you have any ideas about that ... I'll be so pleased for your help !!

No one has mentioned it so far, but I wonder if any of the Great Bridge people were hired by Red Hat? The reason it hasn't been mentioned is that negotiations are still in play.

Why doesn't pg_dump insert commits every 1000 rows or so??? Yup, rant is the correct term.

Re: [GENERAL] Multiple postgresql installations on one machine.
Thanks. I didn't know psql -h did that, thought it was for hostnames only :). So I resorted to TCP access for the rest of the installations and moved the sockets out of the way. However the Redhat style initscript tends to shutdown all installations - even though I specified a different PID file :(. I guess I might need to fix that one - coz the idea is to have them independent. Was actually wondering if I could change the name of the socket to something like ...portnumber.virtual_host_name_or_ip_address That way psql -h vhost1 would try usualprefix.defaultport.vhost1 psql by itself would try usualprefix.defaultport (have to convert dots and slashes in addresses to underscores or something more innocuous, or quote carefully) Probably not that useful now that I know more about -h :).

Re: [GENERAL] Any Good Way To Do Sync DB's?
On 12 Oct 2001, Doug McNaught wrote: Probably the best thing to do is to export the data from Progress in a format that the PostgreSQL COPY command can read. See the docs for details. Hi, I wrote a quick and dirty function/trigger to sync two DBs - one local and the other on the web. The method is quite simple. Any insert or update fires a trigger that serialises the entries and stores it in a log with the table name, the primary key and the timestamp. When an entry is deleted, the same happens except that the serialised column contains a null. So when I sync, I just need to upload the changes and not the entire dump. I think this is a good opportunity to get some advice feedback on the code, so here it is: drop function setuptriggers(); create function setuptriggers() returns int as ' declare fb text; tb text; tresult record; cresult record; pkeynamename; begin for tresult in select * from pg_class where relkind = ''r'' and relname !~ ''^pg_'' and relname !~ ''^Inv'' and relname !~ ''^pga_'' order by relname loop select into pkeyname c.attname from pg_class a, pg_index b, pg_attribute c where a.relname = tresult.relname and a.oid = b.indrelid and a.oid = c.attrelid and b.indkey[0] = c.attnum and b.indisprimary=''t''; if pkeyname is not null and tresult.relname != ''logtable'' then fb := '' create function logchange_'' || quote_ident(tresult.relname) || ''() returns opaque as declare serialized text; updatetime timestamp; separator text; begin updatetime := now; separator := chr(178); serialized := ; ''; for cresult in select * from pg_class a, pg_attribute b where a.relname = tresult.relname and a.oid = b.attrelid and b.attnum 0 order by b.attnum loop fb := fb || '' if NEW.'' || quote_ident(cresult.attname) || '' is not null then serialized := serialized || separator || '' || quote_ident(cresult.attname) || ''= || NEW.'' || quote_ident(cresult.attname) || ''; end if; ''; end loop; fb := fb || '' insert into logtable values (NEW.''|| quote_ident(pkeyname) || '', '' || quote_ident(tresult.relname) || '', serialized, updatetime); return new; end; language plpgsql;''; execute fb; tb := ''create trigger fireon_'' || quote_ident(tresult.relname) || '' before insert or update on '' || quote_ident(tresult.relname) || '' for each row execute procedure logchange_'' || quote_ident(tresult.relname) || ''();''; execute tb; end if; end loop; return 1; end;' language 'plpgsql'; - I hope this is usefule ---(end of broadcast)--- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/users-lounge/docs/faq.html
