Can you connect to the lexicon database and confirm that the correct
databases exist?

e.g. for me (with lexicon jacy):
psql jacy:

jacy=> \ \dt;
             List of relations
 Schema |    Name    | Type  |    Owner
--------+------------+-------+-------------
 public | dfn        | table | bond
 public | lex        | table | bond
 public | lex_key    | table | kuribayashi
 public | semi_extra | table | kuribayashi
 public | semi_frame | table | kuribayashi
 public | semi_mod   | table | kuribayashi
 public | semi_pred  | table | kuribayashi
 public | semi_var   | table | kuribayashi

I think the error message means that the table 'dfn' doesn't exist.

In an ideal world it should look something like this:

jacy => select * from dfn;
 slot  |    field    |              path              |    type
-------+-------------+--------------------------------+------------
 id    | name        |                                | sym
 orth  | orthography |                                | str-rawlst
 unifs | orthography | (stem)                         | str-lst
 unifs | type        | nil                            | sym
 unifs | keyrel      | (synsem lkeys keyrel pred)     | mixed
 unifs | keytag      | (synsem lkeys keyrel carg)     | mixed
 unifs | altkey      | (synsem lkeys altkeyrel pred)  | mixed
 unifs | alt2key     | (synsem lkeys alt2keyrel pred) | mixed
 unifs | altkeytag   | (synsem lkeys altkeyrel carg)  | mixed
 unifs | compkey     | (synsem local cat head ptype)  | mixed
 unifs | idiom       | (idiom)                        | mixed
