In a PL/pgSQL function, there is no command for sharing a common part of the body of several functions, is there?
In my case, I would like a function that returns a numeric value; this value is associated with several other parameters, some numeric and others textual. It would not be practical for maintenance to have several functions (one function for each given parameter) with much of the code being identical.
Presently, I have a text function with all the parameters in return and a function for each parameter based on the first one (with all the parameters), using substr(), position(), etc. For me, I think it would be easier (and perhaps faster) to use some kind of #include in the body of all the functions.
Can you provide some examples of what you are trying to accomplish?
There may be some workarounds using immutable functions other tricks, but I'm not 100% sure I have my head around your issue.
