REPEATABLE is mandated by standard. I did try for quite some time to make it

Yeah, that can be hard to figure out. Did you run bison with -v and
poke around in gram.output?
Oh, no I didn't (I didn't know gram.output will be generated). This
helped quite a bit. Thanks.
I now found the reason, it's conflicting with alias but that's my
mistake - alias should be before TABLESAMPLE clause as per standard and
I put it after in parser. Now that I put it at correct place REPEATABLE
can be unreserved keyword. This change requires making TABLESAMPLE a
"type_func_name_keyword" but that's probably not really an issue as
TABLESAMPLE is reserved keyword per standard.
