Hi,

We have a requirement wherein we have to store around 3 MB of data in
Postgres database.

We had gone through the postgres website
http://www.postgresql.org/docs/7.4/interactive/datatype-character.html#DATATYPE-CHARACTER-SPECIAL-TABLE

The above link says "varchar" can store upto 1 GB of data. But when i try
to insert using ODBC API's the varchar field takes
only 65484 characters. But i could insert more characters using INSERT
SQL command. Even in this case when we fetch the data it reads only 65540
characters. Remaining data is not read from the varchar field.

We have tried in 2 ways

1. table is created without any limit specified for varchar.
create table details (name varchar, data varchar);

2. create table utilntmlscripts (name character varying, data character
varying(10485770));
ERROR: length for type 'varchar' cannot exceed 10485760
It's not allowing more than 10 MB of size during table creation.

Is there anything needs to be configured to make the varchar field to
support upto 1 GB.
Even if it does not support 1 GB, can we store & retrieve atleast 10 MB of
character data
in Varchar field?

Please send the details of how this can be acheived.

Postgres Version 7.4.2
Accessing using UnixODBC driver from C++ application.

thanks,
Vadivel.
