Steven Hawkins commented on TEIIDSB-144:
----------------------------------------
The problem line:
https://github.com/brettwooldridge/HikariCP/blob/109b910fbfc2d95b920fde77...
There is no a pr open to customize the pool behavior -
https://github.com/brettwooldridge/HikariCP/pull/1509
No indication of when that will be picked up.
In the meantime our options are:
- use tomcat jdbc as the pooling mechanism. Similar to
https://github.com/javamelody/javamelody/issues/801 The problems here are that
teiid-syndesis includes pool initialization assuming hikari and that tomcat does no
purging at all, so a test/validation method must be turned on.
- create a proxy layer to trap exceptions that could be a problem
- put a bunch of conditionals in teiid about when to is allowed to make calls that may not
be implemented
- just wait for the fix...
Other than doing nothing, I'd vote for switching to tomcat jdbc. [~rareddy] do you
have a vote?
Calling setTransactionIsolation on pg driver causes the connection to
be closed

Priority: Critical
Fix For: 1.3.1
Original Estimate: 4 hours

An attempt to set the isolation level on pg 42.2.8 resulted in an exception SQLSTATE
0a000 - unsupported - which causes the connection pool to mark the connection as broken:
