PostgreSQLStoredProcedureTest.testProcedureWithJDBCByName
PostgreSQLFunctionProcedureTest.testFunctionWithJDBCByName

fail with similar error using named parameters:

 java.lang.AssertionError: expected:<class java.sql.SQLFeatureNotSupportedException> but was:<class com.edb.util.PSQLException>

while PostgreSQLFunctionProcedureTest could by fixed by referencing parameters in query
sp_count_phones(?,?) → call sp_count_phones(phoneCount=>?,personId=>?)

I didn’t find a similar syntax for PostgreSQLFunctionProcedureTest.
