Parser - keyword cathegory

I'm writing my bachelor thesis and I can't find anywhere what exactly
means the third parameter in ScanKeyword in
pgsql/src/backend/parser/keywords.c - specificly UNRESERVED_KEYWORD,
RESERVED_KEYWORD, TYPE_FUNC_NAME_KEYWORD, COL_NAME_KEYWORD. Could
someone explain it to me? Thank you

It's only a category information. Take a look at (almost at the end of) gram.y
to understand what each category is.

It indicates in what contexts the keyword acts as a reserved keyword, in
other words can't be used as a name for an object without quoting. See
the corresponding rules in gram.y.
