pgsql: Revert ill-considered change of index-size fudge factor. - Mailing list pgsql-committers

Revert ill-considered change of index-size fudge factor.

This partially reverts commit 21a39de5809cd3050a37d2554323cc1d0cbeed9d,
restoring the pre-9.2 cost estimates for index usage.  That change
introduced much too large a bias against larger indexes, as per reports
from Jeff Janes and others.  The whole thing needs a rewrite, which I've
done in HEAD, but the safest thing to do in 9.2 is just to undo this
multiplier change.
