I'm fairly sure that replication workers run with search_path set
to just "pg_catalog" for security reasons. Any user-written code
that needs to execute in a replication worker *must* schema-qualify
all references to non-system objects.
As a general rule, code that runs in expression indexes, check
constraints, and the like needs to be written to not make assumptions
about what search path it's invoked with. Just fix it; your life
will be less painful.
