Postgresql – SymmetricDS fails to start for PostgreSQL 9.2

I'm trying to get SymmetricDS up and running with PostgreSQL.
I've followed the tutorial (almost) exactly.
(I have not set up a separate node yet since, for my purposes, I need that separate node to be truly separate and on a different VM.)
Unfortunately, I am not able to get the database import step to function, as SymmetricDS will not connect to the database.

Following advice from Connecting to local instance of PostgreSQL from JDBC, I ensured that the second SLOC in pg_hba.conf was sensible;
PostgreSQL will (should) accept all connections made over TCP/IP over lo using client-side identification.
(The linked does call for md5 as opposed to ident; this has no visible effect and, according to the stack trace, is probably not what JDBC is expecting.)

I've ensured that symmetricds is a system user and is a user registered with PostgreSQL.
If memory serves, I did this with something like

ADD USER symmetricds WITH PASSWORD sds-pass;
GRANT ALL PRIVILEGES TO test FOR USER symmetricds;

(or something to this effect? I'm very new to databases.)
If I had to guess where I went wrong, it'd be here.

I edited the engine file corp-000.properties to use the PostgreSQL versions of connection details (the file comes set for MySQL) and
I filled in the appropriate credentials.

As far as I know, this is all that is needed to get SymmetricDS up and running (at least for the import step).
Obviously, something went wrong; a stack trace is included below.
What did I miss?
