Message-ID: <E1uz2ks-001FSk-1O@gemulon.postgresql.org> (raw)
Mark shared buffer lookup table HASH_FIXED_SIZE
StrategyInitialize() calls InitBufTable() with maximum number of entries that
the buffer lookup table can ever have. Thus there should not be any need to
allocate more element after initialization. Hence mark the hash table as fixed
sized.
