Well, I applied that patch that you sent me the link to (the bufmgr.c
one), and rebuilt (PORTDIR_OVERLAY is cool...)

I ran my nine processes which hammer things overnight, and in the
morning one of them was dead.

DBD::Pg::st execute failed: ERROR: duplicate key violates unique
constraint "pg_type_typname_nsp_index"
CONTEXT: SQL statement "CREATE TEMPORARY TABLE push_tmp (val text) ON
COMMIT DROP"
PL/pgSQL function "push_func" line 6 at SQL statement

constraint "pg_type_typname_nsp_index"

COMMIT DROP"
PL/pgSQL function "push_func" line 6 at SQL statement

I also write out the time as my processes progress, so I know roughly when
it happened too. It happened at 1136534029 (that's result of perl time()
function), which when run through localtime() yields Thu Jan 5 23:53:49
2006. It looks like I started the processes at about 18:30, so they
lasted a while at least.

Let me know if there is anything else I can try to help debug this
(asserts on?).
