Changes test files in multi and multi-1 schedules such that they
accomodate coordinator in metadata.
Changes fall into the following buckets:
1. When coordinator is in metadata, reference table shards are present
in coordinator too.
This changes test outputs checking the table size, shard numbers etc.
for reference tables.
2. When coordinator is in metadata, postgres tables are converted to
citus local tables whenever a foreign key relationship to them is
created. This changes some test cases which tests it should not be
possible to create foreign keys to postgres tables.
3. Remove lines that add/remove coordinator for testing purposes.
DESCRIPTION: Makes sure to disallow triggers that depend on extensions
We were already doing so for `ALTER trigger DEPENDS ON EXTENSION`
commands. However, we also need to disallow creating Citus tables
having such triggers already, so this PR fixes that.
Fixes https://github.com/citusdata/citus/issues/6394.
DESCRIPTION: Fixes a bug that causes creating disabled-triggers on
shards as enabled
Since CREATE TRIGGER doesn't have syntax support to specify
whether the trigger should be enabled/disabled, the underlying
PG function (`pg_get_triggerdef()`) that we use to generate the
command to create the trigger is not enough. For this reason, we
append a second command to enable/disable trigger, right after
creating it.
We don't retain explicit extension dependencies set by using
`ALTER trigger DEPENDS ON EXTENSION` commands too, but apparently
right fix for that is to throw an error as in
`PreprocessAlterTriggerDependsStmt()`; so, opened a separate PR
to fix that #6399.
This commit brings following features:
Foreign key support from citus local tables to reference tables
* Foreign key support from reference tables to citus local tables
(only with RESTRICT & NO ACTION behavior)
* ALTER TABLE ENABLE/DISABLE trigger command support
* CREATE/DROP/ALTER trigger command support
and disallows:
* ALTER TABLE ATTACH/DETACH PARTITION commands
* CREATE TABLE <postgres table> ATTACH PARTITION <citus local table>
commands
* Foreign keys from postgres tables to citus local tables
(the other way was already disallowed)
for citus local tables.
