If we want to have type decorators mess with the attribute, but not the
column, we need to stop type casting on the column. Where possible, we
changed the tests to test the value of `column_defaults`, which is
public API. `Column#default` is not.
For any type that is represented as a string and then type cast, we do
not need separate regular expressions for the various types. No function
will match this regex. User defined types *should* match this, so that
the type object can decide what to do with the value.

Ensure that SQLCounter.clear_log is called after each test.
This is a step to prevent side effects when running tests. This will allow us to run them in random order.
PostgreSQL escapes single quotes by using an additional single quote.
When Rails queries the column information, PostgreSQL returns the
default values with the escaped single quotes.
#extract_value_from_default now converts these to one single quote each.
Fixes#10881.
In the end I think the pain of implementing this seamlessly was not
worth the gain provided.
The intention was that it would allow plain ruby objects that might not
live in your main application to be subclassed and have persistence
mixed in. But I've decided that the benefit of doing that is not worth
the amount of complexity that the implementation introduced.
In non-strict mode it is '', but if someone is in strict mode then we
should honour the strict semantics.
Also, this removes the need for a completely horrible hack in dirty.rb.
Closes#7780
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.
Selecting which key extensions to include in active_support/rails
made apparent the systematic usage of Object#in? in the code base.
After some discussion in
5ea6b0df9a
we decided to remove it and use plain Ruby, which seems enough
for this particular idiom.
In this commit the refactor has been made case by case. Sometimes
include? is the natural alternative, others a simple || is the
way you actually spell the condition in your head, others a case
statement seems more appropriate. I have chosen the one I liked
the most in each case.
After a long list of discussion about the performance problem from using varargs and the reason that we can't find a great pair for it, it would be best to remove support for it for now.
It will come back if we can find a good pair for it. For now, Bon Voyage, `#among?`.
