It is more complicated than that. The sql module does this:

  do query
  if rows==0:
    do query_alt

The "query" and "query_alt" are normally an update and insert, 
respectively; this helps the SQL module handle missed accounting packets.

The radsqlrelay perl script does not support that mode of operation. 
It's a single query per-packet.

I used postgres stored procedures. The code is too long and 
site-specific to be useful, so little point in me sharing it. It 
basically does

  * all "sql_log" queries are "insert into radacct_packet ()"
  * stored proc is a trigger on radacct_packet table
  * stored proc does the update/insert logic into main "radacct" table

The other option is to just use the new-in-2.0 "listen" "type = detail" 
function and the "real" sql module; see:
