>Thanks a lot!!!

You're welcome

[0-9]+; [0-9]+ [0-9]+ SCHEMA - \b(information-schema|(?!pg_))\w+\b [a-zA-Z]+

There were a couple of problems in your pattern

(1) \w+ will never match information-test because the hyphen is not in the \w set

\w = [A-Za-z0-9_]

(2) You need both the anchors ^ and $ otherwise you may have a match of any sequence of chars in the string

(3) Since (?!) is a zero width assertion you can put both after each other

(?!not this)(?!and not that)
