Hello,
I used different format now. Documentation:
This patch is implementation of variables SQLERRM and SQLCODE for plpgsql
language. Variable SQLCODE contains five chars PostgreSQL Error Code,
SQLERRM contains relevant message last catched exception. All variables
are attached to plpgsql_block and have local scope. Default values are
'00000' for SQLCODE and 'Sucessful completion' for SQLERRM. Some example
of using is in file test.sql.
Regards
Pavel Stehule
