create table bug with reserved words?

There seems to be an inconsistency in the parsing of create table (possibly
other SQL syntax?):

create table test (call int, end, int, select int);
Fails with ERROR: parser: parse error at or near "create"

create table test (call int, end1, int, select1 int);
Works.

Call, End and Select are reserved words, but why does 'Call' work and the
others fail?
Is this a bug - should the parser cope with any reserved words as
identifiers?

Thanks,
Chris
