IBMi to AWS postgreSQL data warehouse

So our non i folks decided to create a small 29 table DWH for a client.
They know little about our tables.
They used symetricDS to pull from the i and populate a staging database.
An ETL tool then moves that to an AWS cloud PostgreSQL data warehouse.

The symDS tool auto generates sql triggers that are slapped on our i
tables. A couple of tables were so large in row size (many columns), that
the auto generated sql triggers were so inefficient that I had to replace
them with an i DB2 trigger that literally hands off the before/after image
to a batch process to carry out the insert of those images to a symDS table
that is also on the i. Apparently the symDS tool pulls changes form that
symDS table on the i.
Then, due to the fact that we have initialized blanks in some of our zoned
fields that sql doesn't play well with, I also had to put our own trigger
on that one... and there may be more eventually.

I'm at the point where I'm convinced this is not the best game plan for the
DWH.

Has anyone got any suggestions for a better IBMi to AWS postgreSQL
replication that would eliminate that symDS staging piece? Preferably
something that can connect directly to the AWS cloud from the i... even if
custom code needs to be written?
