Re: Segfault logical replication PG 10.4

Aha, I see, thanks.  Here's a complete fix with included testcase.  In
an unpatched assert-enabled build, this crashes this

TRAP: FailedAssertion("!(ActiveSnapshotSet())", File: "/pgsql/source/REL_10_STABLE/src/backend/tcop/postgres.c", Line:
788)

Will push on Monday.
