Thread: Problem with array of char

Hi!

I have a serious problem with PostgreSQL 6.3 concerning array of char...
I can create table with array of char2 for exemple, but not array of
char.
create table tab1(a char2[][]);  -> OK
create table tab2(a int2[][]);  -> OK
create table tab3(a char[][]);  -> error...

I can't find it as a known bug and this functionality was possible with
previous version of Postgresql.

Do you have an idea? A solution? I have very large tables and char[][]
is the only way I found to save values of 1 byte (as thin int are not
supported by PostgreSQL).

Thanks!

Stephane

I'm not sure if it's any help, but PostgreSQL has a built-in type called
"bytea", which is a variable-length array of bytes. Maybe you should play
around with it. I'm not sure how values are inserted to it - it seems to
behave very much like the text type.
