I was trying to make a minor change today to the gram.y file to make
PostgreSQL recognize "DOUBLE" as a data type the way DB2 does. I ran into
reduce / reduce conflicts using both of the methods I tried.
Having fought extensively with Bison before on a SQL oriented language
translation project, I am amazed that you were able to get a grammar as
complex as PostgreSQL to work without major difficulty.
I was wondering about what the sense of the list would be to someday accepting
a rewrite using a hand-coded LL(k) recursive descent parser. Anyone?
