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.

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.
