When adding CREATE/DROP DATABASE propagation in #7240, luckily
we've added EnsureSupportedCreateDatabaseCommand() check into
deparser too just to be on the safe side. That way, today CREATE
DATABASE commands from non-main dbs don't silently allow unsupported
options.
I wasn't aware of this when merging #7439 and hence wanted to add
a test so that we don't mistakenly remove that check from deparser
in future.
DESCRIPTION: Adds support for propagating `CREATE`/`DROP` database
In this PR, create and drop database support is added.
For CREATE DATABASE:
* "oid" option is not supported
* specifying "strategy" to be different than "wal_log" is not supported
* specifying "template" to be different than "template1" is not
supported
The last two are because those are not saved in `pg_database` and when
activating a node, we cannot assume what parameters were provided when
creating the database.
And "oid" is not supported because whether user specified an arbitrary
oid when creating the database is not saved in pg_database and we want
to avoid from oid collisions that might arise from attempting to use an
auto-assigned oid on workers.
Finally, in case of node activation, GRANTs for the database are also
propagated.
