two small tab-completion patches (ALTER CONSTRAINT, CHECK modifiers)

[Baji Shaik]

Hello,

Two small ones.
1/ after ALTER TABLE t ALTER CONSTRAINT c, psql offers
nothing so add DEFERRABLE/ENFORCED/INHERIT and their NOT/NO forms.

2/ after ADD [CONSTRAINT c] CHECK (...), psql offers nothing so add NOT
ENFORCED, NOT VALID, NO INHERIT.

Thanks,
Baji Shaik.
