Accurate list of Keywords / Datatypes?

Hi,

While creating a Syntax Highlighting XML for Notepad++ (something like a PLSQL one here http://goo.gl/UBbHdt ), I was looking for a list of Keywords (& separately list of Datatypes) that Postgres uses in a given version (Say DEVEL branch). 

I did find the Reserved Keyword list (http://www.postgresql.org/docs/devel/static/sql-keywords-appendix.html) but it doesn't look like what I need, because:

1. The ones marked as 'Reserved' isn't all the words I am interested in (since these are just 'Reserved')

2. The entire list seems like an overkill (since it has words such as K and ROUTINE_CATALOG, which aren't really what I'd like highlighted when I am working on an SQL file in NPP)

Should I be looking somewhere else? Parse keywords from Git Source file (if so where)? Parse PG Documentation?

I tried ( https://goo.gl/OYeYuE ) parsing HTML Tags (such as VARNAME / TOKEN / LITERAL / COMMAND) in PG Documentation but is there's a simpler (more accurate) way for this?

Any pointers would be great!
