Re: [HACKERS] How to look at the Expression Trees

Hi,

You said:

ExecMakeFunctionResultNoSets is used to evaluate function calls.

What are the 'functions' there? Are they the user supplied pl/PGSQL style
user functions, the functions handled by fmgr or are they just another C
function which make the Expression Evaluator?
