Search engine crashes using operator for partial matches

Entering a search term of "test test*" will crash phpBB with a general error.

General Error
SQL ERROR [ postgres ]

ERROR: invalid input syntax for integer: "w0.word_id" LINE 1: ... (w0.word_text LIKE 'test%') WHERE m0.word_id IN ('w0.word_i... ^ []

=========================================

Entering a search term "test test" with no wildcard (joker) character works as expected.

This bug is a continuation of the discussion from The operator for partial matches does not work .

I am using phpBB Native Fulltext search, postgreSQL.
