Root Cause
java.lang.NullPointerException: Cannot invoke "java.sql.Statement.executeQuery(String)"
because "st1" is null

Tells me nothing more.
The code has to go past the connection and statement lines to get to the query
line.
This code has been working for several years before today.
There is a variable named "st1" in the servlet code which is NULL.
This is not a Postgres error, but an error in your code.
You need to check how st1 is populated in the Java code.
If I had to guess: the code retrieves data from the database and receives a NULL
value that it does not expect and thus not check.
