Hi,

While implementing DROP CONVERSION [CASCADE|RESTRICT], I'm facing
a strange problem. When I tries to delete a tuple from pg_depened, I
got an assertion failure:

TRAP: Failed Assertion("!(!((tp.t_data)->t_infomask & (0x4000 |
0x8000))):", File: "heapam.c", Line: 1315)

This means that HEAP_MOVED_IN or HEAP_MOVED_OFF flag is set. Is this
normal? I noticed that DELETE, INSERT and VACUUM FULL has been
performed over pg_depend in initdb. Is this related to the problem?
