I am inserting some log messages in the column "data". (Basically I am
inserting records from reading an xml file)
In the PRIMARY KEY, btree (scan_id, host_ip, port_num, plugin_id, severity,
data) data is of type TEXT and can contain long string values.
The question is how to remove this error "index row size 2728 exceeds btree
maximum, 2713" by increasing the btree size?
The big problem is "I can not add any additional column in this table."
Thanks

Well - the error message is clear enough. The question is, what to do.
Without knowing what the table "means", it's difficult to say what the
primary-key should be, but it seems unlikely to include an
unlimited-length text-field called "data".
If the data itself doesn't offer any suitable candidate keys (as can
well be the case) then common practice is to generate a unique number
and use that as an ID - in PostgreSQL's case by use of the SERIAL
pseudo-type.
Does that help?
