Ok, here is what I would do if I were facing your problem:
1.- Be sure that each identifier in the database catalogs doesn't
require the double quotes, for instance, for pg_class do something
like:
update pg_class set relname = lower(relname) where relname <> lower(relname);
Do the same for pg_namespace, pg_attribute, etc.
2.- Teach scan.l to treat "Identifier" just as identifier, the
following patch against 7.3 will do the work
*** scan.l~ 2002-11-10 21:33:44.000000000 -0600
--- scan.l 2004-03-30 15:36:23.000000000 -0600
***************
*** 408,414 ****
literalbuf[len] = '\0';
literallen = len;
}
! yylval.str = litbufdup();
return IDENT;
}
<xd>{xddouble} {
--- 408,414 ----
literalbuf[len] = '\0';
literallen = len;
}
! yylval.str = litbufdup_lower();
return IDENT;
}
<xd>{xddouble} {
***************
*** 670,675 ****
--- 670,691 ----
return new;
}
+ static char *
+ litbufdup_lower(void)
+ {
+ char *new;
+ int i;
+
+ new = palloc(literallen + 1);
+ memcpy(new, literalbuf, literallen+1);
+
+ for(i = 0; x < literallen; x++)
+ if (isupper((unsigned char) *(new + i))
+ *(new + i) = tolower((unsigned char) *(new + i));
+
+ return new;
+ }
+
unsigned char
unescape_single_char(unsigned char c)

Manuel.
