Subject: Prevent index-only scans in stats regression test.
X-Git-Url: http://git.postgresql.org/gitweb/?a=commitdiff_plain;h=45401c1c25fe1ef14bf68089de86bcb5cce9f453;p=users%2Fkgrittn%2Fpostgres.git

Prevent index-only scans in stats regression test.

This bollixes the test because it's expecting to see the idx_tup_fetch
counter increase, which won't happen if heap fetches were avoided by use
of an index-only scan.  Per buildfarm results.

While at it, let's just make sure that enable_seqscan and enable_indexscan
are ON for this test ...
