From 88985ca8449d4b535f94e5c5d05cfa9c28f3008c Mon Sep 17 00:00:00 2001 From: Vigneshwaran C Date: Mon, 20 Jun 2022 14:36:51 +0530 Subject: [PATCH v28 2/4] Skip replication of non local data. This patch adds a new SUBSCRIPTION parameter "origin". It specifies whether the subscription will request the publisher to only send changes that originated locally, or to send changes regardless of origin. Setting it to "local" means that the subscription will request the publisher to only send changes that originated locally. Setting it to "any" means that that the publisher sends changes regardless of their origin. The default is "any". Usage: CREATE SUBSCRIPTION sub1 CONNECTION 'dbname=postgres port=9999' PUBLICATION pub1 WITH (origin = local); Even though "origin" parameter allows only "local" and "any" values, it is implemented as a string type so that the parameter can be extended in future versions to support filtering using origin names specified by the user. --- doc/src/sgml/catalogs.sgml | 13 ++ doc/src/sgml/ref/alter_subscription.sgml | 5 +- doc/src/sgml/ref/create_subscription.sgml | 16 ++ src/backend/catalog/pg_subscription.c | 8 + src/backend/catalog/system_views.sql | 4 +- src/backend/commands/subscriptioncmds.c | 43 ++++- .../libpqwalreceiver/libpqwalreceiver.c | 5 + src/backend/replication/logical/worker.c | 2 + src/backend/replication/pgoutput/pgoutput.c | 27 ++- src/bin/pg_dump/pg_dump.c | 15 +- src/bin/pg_dump/pg_dump.h | 1 + src/bin/pg_dump/t/002_pg_dump.pl | 22 +++ src/bin/psql/describe.c | 7 +- src/bin/psql/tab-complete.c | 4 +- src/include/catalog/pg_subscription.h | 17 ++ src/include/replication/pgoutput.h | 1 + src/include/replication/walreceiver.h | 2 + src/test/regress/expected/subscription.out | 142 +++++++++------- src/test/regress/sql/subscription.sql | 10 ++ src/test/subscription/t/032_origin.pl | 155 ++++++++++++++++++ 20 files changed, 426 insertions(+), 73 deletions(-) create mode 100644 src/test/subscription/t/032_origin.pl diff --git a/doc/src/sgml/catalogs.sgml b/doc/src/sgml/catalogs.sgml index 25b02c4e37..dc4b2d3e4c 100644 --- a/doc/src/sgml/catalogs.sgml +++ b/doc/src/sgml/catalogs.sgml @@ -7903,6 +7903,19 @@ SCRAM-SHA-256$<iteration count>:&l + + + suborigin text + + + The origin value must be either local or + any.
