Support for connect_timeout in PQconnectdb()

Hello,

I'm trying to use a postgresql database in a redundant block on v3.0.8 
like so:
 

  redundant {
     pgsql
     detail
     ok
  }


Unfortunately, whenever a request hits this part of the config, it hangs 
for over 120 seconds waiting for the connection to set up before moving 
down the redundant block.  

PQconnectdb() does have a connect_timeout option to configure how long 
the function will wait before returning an error, but I don't see a way 
to configure this in FR.  mod_instantiate() in rlm_sql_postgresql.c looks 
like it only supports the dbname, host, port, user, password, and 
application_name.  

Would it be possible to get a patch that will add a connect_timeout 
option to the rlm_sql_postgresql config?  It would be greatly appreciated.


Thanks,

Kyle
