Hello

a) start by extending some known extension
b) look to source code, where and why a exception was raised. Verbose mode
can help
[pavel@localhost ~]$ psql postgres
psql (9.4devel)
Type "help" for help.
postgres=# \set VERBOSITY v
I create one new type with CREATE TYPE command.

I want use CREATE TYPE to create one type similar to char.
I want to when I create type, then my type behave similar to char:
CREATE TABLE test (oneChar char);
when I want insert one column with length>1 to it, so it gets this error:
ERROR: value too long for type character(1)
I want my type be

I want to create a data type that have tow arguments in the defenition,
like the varchar type:

how can it be done by "CREATE TYPE"

You're out of luck on that. The data types that can have precision

Hallo.
i just coded a new datatype named "cistring", that can be
used in every function that accepts text or varchar, and has
the great ability to be ordered case insensitive in ORDER BY-
Clauses and Indices. The problem is, that its coded like the
text-type, so it is variable length completly.

Can you add LIKE TO CREATE TYPE too ?
There could be also CREATE TYPE ble AS ( LIKE ) , and each colmnu from compose
type will be add to table "ble" with static (NOT) NULL, and without
defaults.
what do you think ?

Can someone point me at some detailed instructions for creating new

I've found quite a few web pages that mention it (in passing) and give brief
examples - but nothing much I can actually work with for my purposes..
Ideally I'd like to use C as the language and the datatype will nee
