Hi there,
we present two variants of GIN fast insert patch, since we're not sure
what is a the best solution:
v0.28.1
- remove disable cost in gincostestimate
- per http://archives.postgresql.org/message-id/499466D2.4010808@sigaev.ru
gingettuple could force cleanup of pending list if it got a lossy tidbitmap.
If such cleanup occurs the gingettuple will rescan pending list again.
v0.28.2
- remove disable cost in gincostestimate
- per http://archives.postgresql.org/message-id/12795.1234379754@sss.pgh.pa.us
AM can now have only one search method: amgettuple or amgetbitmap.
- GIN now has only amgetbitmap interface
