v.in.shape input=x.shp attribute=MBP label=NAME 
should import import shape with two columns. Few modules, like *pg and
db*, can use tables in external db. 
pg.in.dbf should import table to postgres and then you can v.db.reclass
or query with d.what.vect (only in latest cvs)

If you mean point theme based on table x,y then there are d.db and
d.what.db. If you mean to open table as spreadsheet in some GUI interface 
then nothing.

There are some instructions here:
http://grass.itc.it/sqlgrass/odbc_grass_install.html
where "5. You need to create the dbmscap" means that you have to write that
in text editor, but in latest version in cvs dbmscap is not needed.
