Complex order statement fails

#355 Steps to reproduce
We have a table that has fields weight (float) and voterId (integer, foreign key). We would like to sort the results of a query in the following way:
filter.order=["(weight/GREATEST(ABS(weight), 1)) DESC", "voterId ASC", "ABS(weight) DESC"]
Current Behavior
The query breaks with the following error:
error: column "(weight/greatest(abs(weight)" does not exist
at Connection.parseE (.../node_modules/pg/lib/connection.js:581:48)
at Connection.parseMessage (.../node_modules/pg/lib/connection.js:380:19)
at Socket.<anonymous> (.../node_modules/pg/lib/connection.js:116:22)
Expected Behavior
The results are ordered as according to the statement that should be generated.
Additional information
This issue cropped up in 5.x versions of the connector. Perhaps it has something to do with the upgrade of pg?
ADDENDUM: Downgrading to 3.8.3 fixed the problem. 3.9.x exhibited it as well.
I would like to escalate this a little. The reason is, that I'm in a bind now. My old (high sierra) iMac died last week. It seems on Catalina, the 3.8.3 connector is no longer working at all (connection timeouts). This means I can only connect using the 5.0.1 connector, which exposes the bug described in this ticket.

I can report that this error was fixed but only when also using the latest version of loopback-connector.
