What does 'doing that with POSIX' mean? I have read this many times but I do not have a clear understanding.

I meant using something like t.long_text_field ~~ '\mexact phrase\M' in actual sql statement - https://www.postgresql.org/docs/9.5/static/functions-matchin...

I think what he means is "doing it using Unix command line utilities", like grep.
