Re: [SQL] Update is very slow on a bigger table

Tom,

Yes. it looks like there was some locking condition in the database. in
the meantime it disappeared and the updates run quickly. 

thanks for your help. this is the first time i'm working with PostgreSQL
and wasn't sure where to look for possible causes of the problem.

thanks,

dimitar

hi,

its not possible to join cross database tables .
you may keep tables in different schemas instead
of databases.
you may also try contrib/dblink to use tables from
different database.
