Teodor Sigaev	e8cab5fe49	Concurrency for GiST ... - full concurrency for insert/update/select/vacuum: - select and vacuum never locks more than one page simultaneously - select (gettuple) hasn't any lock across it's calls - insert never locks more than two page simultaneously: - during search of leaf to insert it locks only one page simultaneously - while walk upward to the root it locked only parent (may be non-direct parent) and child. One of them X-lock, another may be S- or X-lock - 'vacuum full' locks index - improve gistgetmulti - simplify XLOG records Fix bug in index_beginscan_internal: LockRelation may clean rd_aminfo structure, so move GET_REL_PROCEDURE after LockRelation	20 years ago
