pgsql: Micro-optimization of markpos() and restrpos() in btree and hash - Mailing list pgsql-committers

Log Message:
-----------
Micro-optimization of markpos() and restrpos() in btree and hash indexes.
Rather than using ReadBuffer() to increment the reference count on an
already-pinned buffer, we should use IncrBufferRefCount() as it is
faster and does not require acquiring the BufMgrLock.
