Re: overloading LIKE operator to handle integer + text

Almost. :) The real problem is this, from the manual:

"The operator name is a sequence of up to NAMEDATALEN-1 (63 by default)
characters from the following list:

+ - * / < > = ~ ! @ # % ^ & | ` ?

Grandparent might also want to mark his function as immutable so its
execution can be optimized. Aside from that, this works:

CREATE OPERATOR ~~ (LEFTARG=integer, RIGHTARG=text, PROCEDURE=my_like);

However, this only creates it in the current schema. If this really
should be usable for everyone, this should be the final statement:

CREATE OPERATOR PUBLIC.~~ (LEFTARG=integer, RIGHTARG=text,
PROCEDURE=my_like);
