 Ah missing fields in copy/equal function for AlterSubscriptionStmt.

 Attached patch adds the above mentioned extern and fixes the copy and
 equal functions.

The copyright in some files(tablesync.c and pg_subscriptiion_rel.h)
introduced by this commit are old. Is that intentional? Attached
patch.

 Looks like the clang issue (mylodon, longfin) is because we are missing
 extern in include/replication/worker_internal.h for ApplyCacheContext.

 Still analyzing the rest.

Re: [COMMITTERS] pgsql: Logical replication support for initial data copy

I am looking into buildfarm failures.

Looks like the clang issue (mylodon, longfin) is because we are missing
extern in include/replication/worker_internal.h for ApplyCacheContext.

Still analyzing the rest.

[COMMITTERS] pgsql: Logical replication support for initial data copy

[Peter Eisentraut]

Logical replication support for initial data copy

Add functionality for a new subscription to copy the initial data in the
tables and then sync with the ongoing apply process.

For the copying, add a new internal COPY option to have the COPY source
data provided by a callback function.  The initial data copy works on
the subscriber by receiving COPY data from the publisher and then
providing it locally into a COPY that writes to the destination table.

A WAL receiver can now execute full SQL commands.  This is used here to
obtain information about tables and publications.

Several new options were added to CREATE and ALTER SUBSCRIPTION to
control whether and when initial table syncing happens.

Change pg_dump option --no-create-subscription-slots to
--no-subscription-connect and use the new CREATE SUBSCRIPTION
... NOCONNECT option for that.

The buildfarm is rather upset with this.

Looks like an issue in pg_upgrade / pg_dump.
