I was doing some testing Firebird against wip/6.0 and I tripped over the 
fact the list of keywords in AnsiSqlKeywords.java (introduced for 
https://hibernate.atlassian.net/browse/HHH-9768) is incomplete.

For example, the keyword POSITION is missing from the list, while it is 
listed in SQL:2003 <reserved word>, on the other hand ADD is in the 
list, which is only listed as non-reserved in <non-reserved word>. I 
also notice that most - if not all - other function names are missing.

Firebird is particular finicky about keywords. I see two approaches:

1) I add the difference between the current list in AnsiSqlKeywords + 
DatabaseMetaData.getKeywords() (which only returns those not reserved in 
SQL:2003) and Firebird's actual keywords explicitly in the dialect

2) I update the list in AnsiSqlKeywords to contain all reserved words 
from SQL:2003 (+ retain any additional keywords currently in the list)

This last option would have compatibility consequences (as additional 
keywords may get quoted, which could change case-sensitivity for some 
databases), so that may not be desirable.

Your thoughts on this?
