All user space operators and functions (for appropriate values of "all")
are documented in the respective chapter(s) in the PostgreSQL User's Guide
that is available on the web site and in the source and binary
distributions.
\df in psql shows a lot more functions, but most of these have semi- (or
fully) internal purposes. For example, the "texticregexeq" function is
the internal function that implements the '~*' regular expression matching
operator.
