Description: Assertion Failure
Details:
TRAP: FailedAssertion("!(!(tp.t_data->t_infomask & 0x0800))", File:
"heapam.c", Line: 1410)
This occured during a nightly mainentance run which sets the transaction
isolation level to SERIALIZABLE, moves records from 3 highly active tables
to 3 storage tables by creating a temp table and selecting candidate record
ids into it, then using that list via sub-select for the move ala "insert
into blah_storage (f1, f2, f3) select f1, f2, f3 from blah_active where f1
in (select f1 from move_records_tmp)"
After the move a VACUUM FULL ANALYZE is issued. It appears from the logs
written by the maintenace script that the assertion failure occured during
the vacuum.
I will install RC1 and see if it can be reproduced.
