Subject: [SQL] index row size 2728 exceeds btree maximum, 2713

TABLE

-----------+-----------------------+-----------

  Column    |         Type      

-----------+-----------------------+-----------

 scan_id    | bigint               

 host_ip    | character varying(15)

 port_num | integer              

 plugin_id  | integer               

 severity   | character varying(50)

 data       | text                 

Indexes:

    "pk_scanned_port_info" PRIMARY KEY, btree (scan_id, host_ip, port_num, plugin_id, severity, data)

 

 

On inserting record I am getting this error “index row size 2728 exceeds btree maximum, 2713”

 

How to solve this problem?

Easy, btree indexes can't handle data with more that 2713 bytes.

You need to decide if having a single index on all your columns is
actually what you want. Depending on your queries it may not even be
used.

Hope this helps,
