pgsql: Speed up printing of INSERT statements in pg_dump. - Mailing list pgsql-committers

Speed up printing of INSERT statements in pg_dump.

In --inserts and especially --column-inserts mode, we can get a useful
speedup by generating the common prefix of all a table's INSERT commands
just once, and then printing the prebuilt string for each row.  This avoids
multiple invocations of fmtId() and other minor fooling around.
