<artifactId>postgresql</artifa ctId>

Unsupported major.minor version 51.0

Update on new driver progress
|
| |
Thought I'd give an update for those who are interested. Work has progressed nicely and I have been migrating the original project's unit tests to attempt to reach some level of compatibility between the implementations. Currently about 80% of the unit test have been migrated and only 6 the test are not passing. The failing or erring tests are mostly due to, as yet uncommitted to differences, in the way the drivers work; once permanent decisions are made the driver will be fixed to conform or the test will be updated. Up until now the focus has been on features and conformance but I will be departing from that for a bit to do some performance analysis and enhancement before adding any new features.... more »

JDBC 9.2 DEV not working with Hex bytea output?
|

Hi!
I've downloaded source code for JDBC driver in order to output warnings during development phase of my application (so I can catch triggers messages at client side of the application).
This is the only change I've made (System.out... in addWarning methods - there is two: one for connection, one for statement).... more »

type cache info fix
|
| |
I found that type cache info wasn't honoring search path. (I had a
UDT type that shared a name with a table).
This fixed it.

Patch: Force Primitives
|
| |
...
By default the binary transfers for receive kick in only after the 3rd execution of a prepared statement. Do you see the binary transfers activating for array receives if you run your prepared statement select in a loop?
