Hi all,
I have (recurrent) cache lookup pb in my db and I
didn't find out the solution yet. But, doing a vacuum,
I got the following :
db=# vacuum;
NOTICE: RegisterSharedInvalid: SI buffer overflow
NOTICE: InvalidateSharedInvalid: cache state reset
VACUUM
I have no ideas about possible correlation...
Moreover, and may be of little help, here is a
fragment of a vacuum verbose: this thing seems to be
thrown when vacuuming pg_attribute.
NOTICE: --Relation pg_attribute--

Has anybody seen such a thing before ?
Thanks,
Jeff.
