Re: Porting from PL/SQL to PLPGSQL

Hi Josh,

Thanks for your reply.

In our PL/SQL code we have used userenv('LANG') in some of the INSERT
statements.
Do we have a replacement for this..

Regards

Jomon

PL/pgSQL currently does not handle exceptions at all. This is on the TODO
list.

There are several variables and tools which provide current user and session

information. See the "PostgreSQL Administration" section of the
documentation.

In Postgres, this is generally done through the RULES system instead of
triggers. Please lookup CREATE RULE in the online docs.
