When doing a large query from either an OpenACS 3.2.2 web page (/intranet/e=
mployees/admin/index.tcl) or from psql, I get the following error:=20
NOTICE:  PortalHeapMemoryFree: 0x0x41a37610 not in alloc set!
NOTICE:  PortalHeapMemoryFree: 0x0x41a37cc8 not in alloc set!
NOTICE:  PortalHeapMemoryFree: 0x0x41a37ca0 not in alloc set!
ERROR:  btree scan list trashed; can't find 0x0x41a37bf0


The PostgreSQL.org doxlist faq says the following...=20
5.2) What does the message "NOTICE:PortalHeapMemoryFree:=20
0x402251d0 not in alloc set!" mean?

You are pfree'ing something that was not palloc'ed.=20
Beware of mixing malloc/free and palloc/pfree.=20


...I'm not sure what to do with this information.

The postmaster process looks like so=20
  PID TTY      STAT   TIME COMMAND
  476 ?        S      0:04 /usr/local/pgsql/bin/postmaster -B 1000 -S -o -S=
 8000 -D/usr/local/pgsql/data
Other inserts and queries can be run in this and other databases through ps=
ql or from other OpenACS web pages.
Thanks for your help.=20

The troublesome query (either half of the union can be run successfully):=
