Hello,
I found easy implementation of variadic functions. It's based on
adapation FuncnameGetCandidates. When I found variadic function, then
I should create accurate number of last arguments (diff between
pronargs and nargs). Variadic function can be signed via flag or via
some pseudotype. Flag is better - allows variadic arguments of any
type. In static languages (like SQL or PL/pgSQL) variadic variables
can ba accessed via array (variadic arguments can be only nonarray).
This isn't problem in C language, there are arguments available
directly.
There are a whole slew of questions around this, ISTM.
For example: What will be the type inferred for the array of variadic
args in plpgsql?
If we are going to do this I think we need some discussion on design
before we rush into it.
cheers
