I'm trying to create a custom type (PostgreSQL 9.0) which will essentially auto truncate a string to a certain length.
The type (auto_trunc_char) will be used as follows:
Create table blah (
Some_name auto_trunc_char(40)
)
Can this be done purely in plpgsql?
If so, how?
I know I have to declare the following (at least) but I'm not sure how to flesh
out the functions:
create type auto_trunc_char (
INTERNALLENGTH = VARIABLE,
INPUT = auto_trunc_char_in_function,
OUTPUT = auto_trunc_char_out_function,
TYPMOD_IN = auto_trunc_char_modifier_in
);

Russell Keane
