I read the posts on pgsql functions and transactions from the Novice list, and I think they are saying "PGSQL functions
donot support transactions". Is this correct? Or is the idea that functions are automatically in a transaction?
My functions are processing a lot of data, and I'm getting the following error after 2 hours of processing on my
developmentbox:
WARNING: ShmemAlloc: out of memory
WARNING: Error occurred while executing PL/pgSQL function get_facility_percentiles
WARNING: line 37 at execute statement
ERROR: LockAcquire: lock table 1 is out of memory
I thought if I put begin transaction/commit transaction around pieces of the functions, the database could let go of
somelocks and I could process all the way through, as well as preserve some of the results. As it is now, I believe all
theresults are rolledback after the memory error. However, I cannot seem to get the begin transaction/commit in the
correctplaces.
Any insight and/or assistance with how to solve this memory problem/rollback issue would be greatly appreciated.
Best Regards,
