If you're using PostgreSQL and you're seeing errors like these

✕ C08 created_at                 TIMESTAMPWITHTIMEZONE (timestamptz)                                   NOT NULL  →  Timestamp
    TIMESTAMPWITHTIMEZONE (timestamptz) is not coercible to Timestamp
    according to the JDBC specification or any defined mapping. Fix
    this by changing the schema type to TIMESTAMP; or the Scala type
    to an appropriate object type.

It's probably because you're using doobie.util.meta.LegacyInstantMetaInstance somewhere to provide Meta[Instant] and it is complaining because this legacy instance uses java.sql.Timestamp under the hood. java.sql.Timestamp is ill-specified and should be avoided.

You should switch to use Meta[Instant] in doobie.postgres.JavaTimeInstances instead, where assumes driver-native support for Java 8 types.
