Schema names with reserved words such as "create" will fail this query without double quotes.
Attempted prepared statement with ? placeholder. This failed with the following CakePHP error:
Error: A Database connection using "Postgres" was missing or unable to connect.
The database server returned this error: SQLSTATE[42601]: Syntax error: 7 ERROR: syntax error at or near "$1" LINE 1: SET search_path TO $1 ^
This statement does not serve a purpose anymore.
In a long forgotten world it indicated the main version number of PHP which the code in the file was compatible to.

But since PHP 5.1 and later this is only marginally true.
Thus I propose to remove it from CakePHP.
Add into the tower of hacks that is the SQL generation and stop breaking
COUNT(DISTINCT foo) style queries. Previously these would be converted
into DISTINCT COUNT(foo) which will give the non-distinct results.
When calling flushMethodCache it correctly empties self::$methodCache but if cacheMethod is called afterwards self::$methodCache gets populated with data from the Cache.
The value function quoted a null value as N'' instead of NULL.
As a result is produced queries like [name] IS N'' instead of [name] IS NULL which resulted in an SQL error.
generate bigint primary keys correctly. Autoincrement cannot be set as
it only works with INTEGER columns[1]. I decided to use some string
manipulations as the entire SQL generation bits are a bit janky and I've
already re-written them for 3.0.

Closes #GH-1552
It now fails in PHP >= 5.5.2 . Also it never did anything in earlier
versions as the session would have already been started if auto_start
was true.
Fixes#4010
`sqlite_sequence` is a dynamic table that's only available when a table in
the database use an auto increment field. For some cases, eg: databases that
exclusively use uuid for primary keys, this table won't exist and
truncate() call will fail with:
Error: SQLSTATE[HY000]: General error: 1 no such table: sqlite_sequence
