Subject: A function to count all ocurrences of a character within a string.

Hello pgsql community,

Is there any string function (other than regex / scan & compare loop) to 
obtain a list (or even a count) of characters within a string?
strpos and position seems to return only first occurence of a 
char/string within substring.
The goal is to check if a string contains equal number of opening and 
closing parenthesis, and if there are any of them.

Regards,

Piotr Czekalski
