for some reason i can't make it work.
i've installed and configured odbc. asterisk tells me it's connected:

*CLI> odbc show 

ODBC DSN Settings                                                                                             

  Name:   asterisk                                                                                            
  DSN:    asterisk                                                                                            
    Last connection attempt: 1969-12-31 19:00:00                                                              
  Pooled: No                                                                                                  
  Connected: Yes  

i've changed extconfig.conf as follows:
ps_endpoints => odbc,asterisk 

Now asterisk logs the following: 
WARNING[966]: config.c:2905 find_engine: Realtime mapping for 'ps_endpoints' found to engine 'odbc', but the engine is not available
and don't see any queries in database log. Am I doing something wrong?

Yes, it seems to deadlock in res_config_pgsql. 
I've opened an asterisk issue here: https://issues.asterisk.org/jira/browse/ASTERISK-25455
Will see where it goes.
