should update dependency pg-types which depends on deprecated api

[loynoir]

Detail

• [email protected] depends on "pg-types": "^1.12.1"

• [email protected] depends on "postgres-bytea": "~1.0.0", and newest is 4.0.1

• [email protected] use new Buffer(input.substr(2), 'hex'), and newest is 3.0.0

• Buffer() constructor is deprecated

Suggestion

I think it might be better using workspaces, or said monorepo. So it might be easier to keep relative repo up to date.

Or use something like dependency bot.
