Hello,
I am defining new types for PG. First I define IO and types and then
relation functions and on the end operators. While defining operators I
get strange NOTICE messages:
...
Query sent to backend is "define operator << ( arg1 = nlschar, arg2 = nlschar, procedure = nlschar_lt, associativity = left, restrict = intltsel, join = intltjoinsel) "
DEFINE
Query sent to backend is "define operator >> ( arg1 = nlschar, arg2 = nlschar, procedure = nlschar_gt, associativity = left, commutator = <<, restrict = intltsel, join = intltjoinsel) "
NOTICE:Aug 1 12:58:26:buffer leak detected in BufferPoolCheckLeak()
NOTICE:Aug 1 12:58:26:[00] (freeNext=18, freePrev=19, relname=pg_operator, blockNum=2, flags=0x14, refcount=0 0)
NOTICE:Aug 1 12:58:26:[01] (freeNext=47, freePrev=7, relname=pg_log, blockNum=0, flags=0x14, refcount=0 0)
... much more NOTICE:
NOTICE:Aug 1 12:58:27:[63] (freeNext=15, freePrev=54, relname=pg_procnameind, blockNum=3, flags=0x14, refcount=0 0)
DEFINE
This happens on definition each second operator. What does it mean ?
Does I am making any thing wrong ?
Thank You
Wojtek

Hi,
The "buffer leak" notices seem to be caused by an internal problem of
postgres, not by the user. I have gotton a bunch of these notices once,
when I ran the regression test, but could not reproduce the problem.
The problem was not reproducable, though. If anybody has a set of
queries, which reproducably produce a buffer leak, I would appreciate,
if you send me them.
Kai

yes. a piece of code is pinning a buffer somewhere and then neglecting
to unpin it again. the scary notices were added to facilitate debugging.
i thought the define operator one had been fixed. maybe not. there is a
new one lurking in the btree code somewhere..
