What version of Postgres and where did you get it?
OS and version?
Which logs?

A timeout expired, probably on client side.
Where are the clients relative to the server, local network or Internet?

Where are the above coming from as I can not find a reference to
readCurIndex in either the Postgres or psqodbc code?

Another timeout.

Looks like bad code in IsDuplicateSelect ID is triggering an exception
that shuts down the database.

I am not seeing that in what you show. In any case that is what a unique
constraint is supposed to do, throw an error when you try to create a
duplicate entry. The client/application code will need to be able to
deal with that.

Looks like some external process is shutting down the server.

The only thing I understand in the above is:

"...the free memory (89677824 bytes) is less than 5% of total memory."

Whatever it is wants more memory.
