Now, connection handles the check for valid types so that each database can handle the changes individually.

A patch was committed recently which quoted the extension name in the SQL for `enable_extension`. But the same wasn't done for `disable_extension`.

The use of quotations is required to install extensions with certain
characters in them (e.g. uuid-ossp).

Closes #9480.
We use `TableDefinition` for `#create_table` and `Table` for `#change_table`.
The PostgreSQL sepcifc types were only defined on `TableDefinition` so I
also added them to `Table`.

|
|
|

|
| |
We should only type cast when we need to use.

This reverts commit 5d528f835e871f5f9d4b68e8a81cfbe900b7e718.
Relates to f8c8ad5 which is also getting reverted due to failing test.

in the new 'variables:' hash in each database config section in database.yml.
The key-value pairs of this hash will be sent in a 'SET key = value, ...'
query on new database connections.
The configure_connection methods from mysql and mysql2 into are

Remove parsing of character type default values for 8.1 formatting since
Rails doesn't support postgreSQL 8.1 anymore.
Remove misleading comment unrelated to code.

According to postgreSQL documentation:
(http://www.postgresql.org/docs/8.2/static/catalog-pg-attrdef.html)
we should not be using 'adsrc' field because this field is unaware of
outside changes that could affect the way that default values are
represented. Thus, I changed the queries to use
"pg_get_expr(adbin, adrelid)" instead of the historical "adsrc" field.

PostgreSQL adapter properly parses default values when using multiple
schemas and domains.
When using domains across schemas, PostgresSQL prefixes the type of the
default value with the name of the schema where that type (or domain) is.
For example, this query:
```
SELECT a.attname, d.adsrc
FROM pg_attribute a LEFT JOIN pg_attrdef d
ON a.attrelid = d.adrelid AND a.attnum = d.adnum
WHERE a.attrelid = "defaults"'::regclass
AND a.attnum > 0 AND NOT a.attisdropped
ORDER BY a.attnum;
```
could return something like "'<default_value>'::pg_catalog.text" or
"(''<default_value>'::pg_catalog.text)::text" for the text columns with
defaults.
I modified the regexp used to parse this value so that it ignores
anything between ':: and \b(?:character varying|bpchar|text), and it
allows to have optional parens like in the above second example.

If your database supports setting the isolation level for a transaction,
you can set it like so:
Post.transaction(isolation: :serializable) do
# ...
end
Valid isolation levels are:
* `:read_uncommitted`
* `:read_committed`
* `:repeatable_read`
* `:serializable`
You should consult the documentation for your database to understand the
semantics of these different levels:
* http://www.postgresql.org/docs/9.1/static/transaction-iso.html
* https://dev.mysql.com/doc/refman/5.0/en/set-transaction.html
An `ActiveRecord::TransactionIsolationError` will be raised if:
* The adapter does not support setting the isolation level
* You are joining an existing open transaction
* You are creating a nested (savepoint) transaction
The mysql, mysql2 and postgresql adapters support setting the
transaction isolation level. However, support is disabled for mysql
versions below 5, because they are affected by a bug
(http://bugs.mysql.com/bug.php?id=39170) which means the isolation level
gets persisted outside the transaction.

Having column related schema dumper code in the AbstractAdapter. The
code remains the same, but by placing it in the AbstractAdapter, we can
then overwrite it with Adapter specific methods that will help with
Adapter specific data types.
The goal of moving this code here is to create a new migration key for
PostgreSQL's array type. Since any datatype can be an array, the goal is
to have ':array => true' as a migration option, turning the datatype
into an array. I've implemented this in postgres_ext, the syntax is
shown here: https://github.com/dockyard/postgres_ext#arrays
Adds array migration support
Adds array_test.rb outlining the test cases for array data type
Adds pg_array_parser to Gemfile for testing
Adds pg_array_parser to postgresql_adapter (unused in this commit)
Adds schema dump support for arrays
Adds postgres array type casting support
Updates changelog, adds note for inet and cidr support, which I forgot to add before
Removing debugger, Adds pg_array_parser to JRuby platform
Removes pg_array_parser requirement, creates ArrayParser module used by
PostgreSQLAdapter

This implements the support to encode/decode JSON
data to/from database and creating columns of type
JSON using a native type [1] supported by PostgreSQL
from version 9.2.
