(Pavan Deolasee, Tom Lane)
</P

that depends on a column not previously indexed, then rows
updated by transactions that ran concurrently with

reliable solution is to rebuild affected indexes after installing
this update.

tried to transform away AND/OR/NOT operators appearing below a PHRASE
operator; instead upgrade the execution engine to handle such cases
correctly. This fixes assorted strange behavior and possible crashes
for text search queries containing such combinations. Also fix
nested PHRASE operators to work sanely in combinations other than
simple left-deep trees, correct the behavior when removing stopwords
from a phrase search clause, and make sure that index searches behave
consistently with simple sequential-scan application of such queries.
