So channel_mapping references autenticazionesocial. The error message
you gave previously indicates that there is more than one entry in
channel_mapping referencing idautenticazionesocial=1622 in
autenticazionesocial.
So are you positive channel_mapping has no entries left that have
idaut=1622?
Also, to help with troubleshooting, what version of Postgres are you using?
