pgsql: Improve bulk-insert performance by keeping the current target - Mailing list pgsql-committers

Log Message:
-----------
Improve bulk-insert performance by keeping the current target buffer pinned
(but not locked, as that would risk deadlocks).  Also, make it work in a small
ring of buffers to avoid having bulk inserts trash the whole buffer arena.

Robert Haas, after an idea of Simon Riggs'.
