Message-ID: <E1rtD7P-000r8g-SX@gemulon.postgresql.org> (raw)
BitmapHeapScan: begin scan after bitmap creation
Change the order so that the table scan is initialized only after
initializing the index scan and building the bitmap.
This is mostly a cosmetic change for now, but later commits will need
to pass parameters to table_beginscan_bm() that are unavailable in
ExecInitBitmapHeapScan().
