Parse error at or near char

Hi Again,

While implementing the DBD-Pg-0.63 package, I ran their set of 33 tests.
The sequence failed on the second test with a fatal error that appears to
originate in PostgreSQL. I extracted test 2 from their test.pl file
and set it up to run like a Postgres regression test (shown at the end
of this post). The problem manifests itself as a 'parse error at or near
"char"'. Column 2 in the "builtin" table was assigned the name
"char". I changed it to "CHAR"; it still failed. I changed it
to "xhar" and it passed; but test 5 reported "not OK" and test 29 failed
from an unrelated cause. Using "khar", only test 29 failed. If I comment
out test 29, all of the other tests report OK. The names "cookie" and
"cook" are OK; it seems that only the word "char" offends test 2.

I did run the Postgres regressions test and the characters test all
passed! Flex on my system is at 2.5.3 and bison is at 1.22 . Are
these ok? What other utility version numbers should I check? Do
I have a configuration problem or is this a PostgreSQL bug?

Regards,
Albert
