New comment. This func/column things has always confused me.
/*
* parse function
* This code is confusing because the database can accept
* relation.column, column.function, or relation.column.function.
* In these cases, funcname is the last parameter, and fargs are
* the rest.
*
* It can also be called as func(col) or func(col,col).
* In this case, Funcname is the part before parens, and fargs
* are the part in parens.
*
*/
Node *
ParseFuncOrColumn(ParseState *pstate, char *funcname, List *fargs,
bool agg_star, bool agg_distinct,
int precedence)
