…ypes (#143)

* CockroachDB default types

In cockroachdb, the default values returns something like `field:::TIMESTAMPZ`, and the validation here is only by the default value, without its type, this regex is required.

* - considering column aliases for type checking in AlterColumn method

* Merging cockroachdb + postgreSQL regex together. It work in all these cases:
`'field'::character varying`
`'field':::character varying`
`field::character varying`
`field:::character varying`
