No support for function overloading

[prog8]

Version

1.27.0

What happened?

I have Postgresql schema where I define overloaded function to handle many column types.

CREATE FUNCTION foo(text)
CREATE FUNCTION foo(text[])

Unfortunately during schema parsing sqlc returns an errors saying that function foo already exists which is not true. The function is in fact defined by full signature, not just the name.

Relevant log output

relation "foo" already exists

Database schema

CREATE FUNCTION foo(text)
CREATE FUNCTION foo(text[])

I looked at details and it seems the problem is just text vs text[]. If I try with completely different type like text vs number the problem disappears. This makes me think that that in fact there is signature check but for some reason text is confused with text[] like they are the same type.
