If a new type is introduced as an alias to a built-in type like CREATE DOMAIN money2 AS NUMERIC(12,2); then it is not correctly handled in io.debezium.connector.postgresql.PostgresValueConverter.convertBinary(Column, Field, Object).
The issue is visble in snapshot as the value arrives as the logical Java class and is not thus possible to be converted as a binary value.

See https://issues.jboss.org/browse/DBZ-1009?focusedCommentId=13757501&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13757501 for reference.

Key problems

• streaming mode delivers byte representation but snapshot mode delivers Java class
• how to handle default values?
