[PostgreSQL-Hackers] Failed assertion, CVS head

Hi,

I am using a version of PostgreSQL compiled from a CVS update of yesterday,
and compiled with
make clean all
make install

One client connection to the database doing routine and low volume
population
scripts (using schemas) After several normal runs of the population
script, a
run caused the following trap, and an associated backend halt.

TRAP: FailedAssertion("!(((ntp)->t_data)->t_infomask & 0x0010)", File:
"catcache.c", Line: 1728)

I know this is not a lot of data for a determination of cause, but I
have only
had a single instance of this happening, and thought it should at least be
documented.

Regards,
Grant

This seems moderately impossible :-(. Did you get a core dump? If so
please provide a stack backtrace.

I'm afraid that I did not get a core dump. Sorry.
My normal configure includes both debug and cassert - is there anything
else I should set to ensure core dumps are generated?

Check "ulimit -c" in the postmaster's environment.

Personally I always put "ulimit -c unlimited" into the postmaster start
script.
