For MySQL/Sqlite, using mwtinyint instead of bool, in reality it doesn't
matter since bool is an alias of tinyint(1) in MySQL.
In Postgres:
- Changing type of site_domain from TEXT to VARCHAR to make it in sync
with MySQL/Sqlite
- Renaming all indexes from site_* to sites_* to be in sync with
MySQL/Sqlite

Sqlite doesn't need any change as binary/varbinary both turn into BLOB.
For Postgres:
- Dropping foreign key on pr_page, as all FKs should be dropped (See
T164898)
- Add all of indexes, it seems PG was missing all four indexes of the
MySQL version and didn't have any
- Changing PK from (pr_page,pr_type) to (pr_id).
- Had to add changePrimaryKey function to handle such cases, similar
to checkIndex
- Set pr_page to not nullable

Yes, name of that table is really querycachetwo.
For migrating MySQL/Sqlite, changed data type of qcc_title and
qcc_titletwo to varbinary.
For migrating Postgres, just renaming indexes to stay in sync with
MySQL/Sqlite was enough.

Turning qc_title to varbinary in MySQL to make it consistent with the
rest of fields.
For Postgres:
- Setting 0 as default for qc_value and qc_namespace

Also fixing one schema data type drift between MySQL and Postgres
and fixing the problem with booleans, currently DBAL turns "boolean" to
TINYINT(1) in MySQL because it doesn't support it but it leave it like
that in Postgres which in turn breaks it because mediawiki currently
doesn't cast values properly, so for now just turning them to SMALLINT
which is the status quo (See T257755#6335566)

Put a single blank line between a CREATE TABLE and each accompanying
CREATE INDEX, but two blank lines between those statements and the next
CREATE TABLE.
Change-Id: I8ae8a3c808a772a338e968213031d390bf1b31ca
Previously, a first str_replace() would add a single newline before any
CREATE (TABLE or INDEX), and then a second one would add another newline
after the $wgDBTableOptions, resulting in a blank line between any two
CREATEs and also a newline at the end of the file – at least for MySQL
schemas. But PostgreSQL and SQLite schemas don’t use $wgDBTableOptions,
so the second str_replace() was a no-op for them, and they got no blank
line between CREATEs nor a newline at the end of the file. Fix this by
making the first str_replace() insert two newlines and appending a final
newline all the time.
