This WARNING appeared because SearchSysCacheLocked1() read
cc_relisshared before catcache initialization, when the field is false
unconditionally. On the basis of reading false there, it constructed a
locktag as though pg_tablespace weren't relisshared. Only shared
catalogs could be affected, and only GRANT TABLESPACE was affected in
practice. SearchSysCacheLocked1() callers use one other shared-relation
syscache, DATABASEOID. DATABASEOID is initialized by the end of
CheckMyDatabase(), making the problem unreachable for pg_database.
Back-patch to v13 (all supported versions). This has no known impact
before v16, where ExecGrant_common() first appeared. Earlier branches
avoid trouble by having a separate ExecGrant_Tablespace() that doesn't
use LOCKTAG_TUPLE. However, leaving this unfixed in v15 could ensnare a
future back-patch of a SearchSysCacheLocked1() call.

pg_authid's only varlena column is rolpassword, which unfortunately
cannot be de-TOASTed during authentication because we haven't
selected a database yet and cannot read pg_class. By removing
pg_authid's TOAST table, attempts to set password hashes that
require out-of-line storage will fail with a "row is too big"
error instead. We may want to provide a more user-friendly error
in the future, but for now let's just remove the useless TOAST
table.
Bumps catversion.

An upcoming test needs to use a tablespace as part of its test. Historically,
we wanted tablespace creation be done in a dedicated file, so it's easy to
disable when testing replication. But that is not necessary anymore, due to
allow_in_place_tablespaces.
Create regress_tblspace tablespace in test_setup. Move the tablespace test to
the end of the parallel schedule, so other tests can use it.

The clauses SET TABLESPACE and ALL IN TABLESPACE are supported in ALTER
MATERIALIZED VIEW for a long time, and they behave mostly like ALTER
TABLE by reusing the same code paths, but there were zero tests for
them. This commit closes the gap with new tests in tablespace.sql.

Using this system function with an in-place tablespace (created when
allow_in_place_tablespaces is enabled by specifying an empty string as
location) caused a failure when using readlink(), as the tablespace is,
in this case, not a symbolic link in pg_tblspc/ but a directory.
Rather than getting a failure, the commit changes
pg_tablespace_location() so as a relative path to the data directory is
returned for in-place tablespaces, to make a difference between
tablespaces created when allow_in_place_tablespaces is enabled or not.
Getting a path rather than an empty string that would match the CREATE
TABLESPACE command in this case is more useful for tests that would like
to rely on this function.
While on it, a regression test is added for this case. This is simple
to add in the main regression test suite thanks to regexp_replace() to
mask the part of the tablespace location dependent on its OID.

Remove the machinery from pg_regress that manages the testtablespace
directory. Instead, use "in-place" tablespaces, because they work
correctly when there is a streaming replica running on the same host.

"git mv" all the input/*.source and output/*.source files into
the corresponding sql/ and expected/ directories. Then remove
the pg_regress and Makefile infrastructure associated with
dynamic translation.
