That's a bit interesting ... what PG version is this exactly?
"PostgreSQL 8.1.4 on i686-pc-mingw32, compiled by GCC gcc.exe (GCC) 3.4.2 (mingw-special)"
What else might be touching that table at the same time?
Maybe some other client executes same or other command at same time in same database. templsabi table is created, dropped and updated frequently by a number of clients concurrently.
Do you have autovacuum enabled?
Yes.Andrus.
