I'monly working with a few tens of lines, so I can read them all into R and examine them 1-by-1, but I thought I would
ask.

Something like

    ... WHERE mystring ~ ANY (SELECT regex FROM regexes)

should do.

            regards, tom lane

Actually, all I needed to do was to reverse the input text and the column name in the query:

    SELECT DISTINCT group_id FROM logins WHERE '[user_email]' ~* email_regex;
