Hello,

I've got a failing sql-Script that I execute with the psql command. The Script contains:

I've been unable to reproduce the error with just that snippet (on debian with PostgreSQL 8.1.4). Can you provide a stripped down test case?

Reproduction is difficult. The script runs fine with the same db on another server with a Linux derived from Knoppix, but also postgresql 8.1.4.

PANIK:  ERRORDATA_STACK_SIZE exceeded

        This probably means the server terminated abnormally

'Exceeding stack size' sound somewhat like an infinite loop of a recursive function... but that's just a very general guess. I think the root cause of problems is somewhere else.

As I see it, ERRORDATA_STACK_SIZE is a constant that is defined in the code (pgsql/src/backend/utils/error/elog.c) as 5. 5 illegal bytecodes that postgresql finds in my statement are enough to cause the panic.
