This looks like it must be a memory leak in the gist indexing code
(either gist itself or tsearch2). I don't see any post-release fixes in
the 7.4 branch that look like they fixed any such thing :-(, so it's
probably still there in 7.4.7, and likely 8.0 too.
Jean-Gerard, can you put together a self-contained test case? I suspect
it need only look like "put some data in a table, make a tsearch2 index,
delete half the rows in the table, VACUUM FULL". But I don't have time
to try to cons up a test case right now, and especially not to figure
out what to do to duplicate your problem if it doesn't happen on the
first try.
