Hi Christoph,

Thanks for the quick reply. I have placed my PL/SQL into a file. So at
command line (after logging in using psql and getting the Postgresql
prompt), how do I run the entire PL/SQL in the file? 

So I gather there is no compilation of PL/SQL under PostgreSQL (unlike
ORACLE). One would just have to call the PL/SQL using SELECT statement
and if it works, it means its OK? If it hits an error, how do I get
error codes out? ORACLE PL/SQL can return error codes via SQLERRM and
SQLCODE variables accessible within the PL/SQL? Does PostgreSQL also
return the same error codes via accessible variables?

Thank you & best regards

Hi

you can do it at the command line:
open a shell, change to your dbuser, then
psql mydb
or psql mydb -u USER -h HOST

Or install pgAdminIII, a common GUI for postgres (I prefer the
commandline.)
If you use the commandline, make sure readline-support is installed.

If you run (on the shell) your "CREATE OR REPLACE FUNCTION"-Statement,
that's it. After this, you call your new function like this:

select myfunc(arg);

since functions are polymorphic, you have to use the appropriate amount
of arguments, otherwise you will get the message that this function does
not exist...

yours,
Christoph
