Description: user-defined function in transaction

Details:

User-defined function is called inside transaction block (begin end) in php
script. There is loop in php script where this PL/pgsql functon is invoked
several times. On first iteration it cause no mistake, on second it cause
mistake like this:

ERROR: relation with OID 165645734 does not exist
CONTEXT: PL/pgSQL function "session_recount_time_sec" line 35 at select
into variables
ERROR: current transaction is aborted, commands ignored until end of
transaction block

And it doesn't depend on input data. On first loop it's always OK and then
it's always error
