pgsql: Fix operator typo in tablecmds.c

Fix operator typo in tablecmds.c

A bitwise operator was getting used on two bools in
ATAddCheckConstraint() to track if constraints should be merged or not
with the existing ones of a relation, though obviously this should use
a boolean OR operator. This led to the same result, but let's be
clean.

Oversight in 074c5cf.
