Subject: Mark the text_soundex() function as "strict", to avoid crashing on NULL
X-Git-Url: http://git.postgresql.org/gitweb/static/gitweb.js?a=commitdiff_plain;h=c40f9906ff7127bc34885ae984e7645fc925cda0;p=users%2Fbernd%2Fpostgres.git

Mark the text_soundex() function as "strict", to avoid crashing on NULL
input. Also, may as well mark it "cacheable" as well. From Kris Jurka.
