Re: [SQL] Split a string to rows?

2013-01-08 Thread Emi Lu

Hello Thomas,


Thanks a lot! I just noticed that my postgresql is 8.3(unnest
function is not there by default). Is there a way that I could
download and load only this function from somewhere?



Are you aware that 8.3 will be de-suppported as of next month?

You should really think about an upgrade *now*



http://www.postgresql.org/support/versioning/

Although 8.3 reaches EOL date, it says that Supported=Yes for 8.3.

I believe that Supported would be fine, wouldn't it?

Emi

Hi Emi,

It will be supported until February 2013. You have about 1 month left.

Regards,
Ken

It is supported until February (or more precisely, until the next
point release after then, which will be the final wrapup release). At
that point, there will be no more releases or bug fixes.

Start thinking about upgrading now, as Thomas suggests.

[SQL] copy users/groups

2013-01-08 Thread Edward W. Rouse
We have a database that was updated from 7.4.1 to 9.1.3. I've gotten
everything working, but now it seems that the users and groups weren't
restored. Probably because they weren't backed up. Is there a way to dump
just the users and groups, plus the passwords and permissions, and restore
them without overwriting what's been manually added to the new database?

Users/groups i.e roles are global to a cluster, you need to use pg_dumpall:

http://www.postgresql.org/docs/9.1/interactive/app-pg-dumpall.html

pg_dumpall -g

Will dump only the global items.

[SQL] How to generate drop cascade with pg_dump

2013-01-08 Thread Emi Lu

Hello,

May I know how to generate drop table cascade when pg_dump a schema please?

E.g.,
pg_dump -h db_server -E UTF8   -n schema_name  -U schema_owner --clean 
-d db_name ! ~/a.dmp


In a.dmp, I'd like to get:

drop table t1 cascade;
drop table t2 cascade;
... ...

Only dropping constraints within a schema is not good enough since there 
are dependencies on other schema.


Thanks a lot!
Emi
