What about reduce and shift conflicts, any bison expert here?

Shift/reduce and (for GLR parsers, which that sqlbison.y is) reduce/reduce conflicts are somewhat common and expected, so there's even %expect and %expect-rr declarations that specify the number of expected sift/reduce and reduce/reduce conflicts, respectively, and Bison will then only warn if the numbers are wrong. Though, of course, somebody familiar with that sqlbison.y should probably have a look before blindly adding such declarations to silence the warnings.
