I would imagine IBM, et al stick to the jdk specs (or should be) and so long as we don't use any vendor specific extensions then it should work across the board. Even if it doesn't I imagine many of the other versions are commercial offering for which I don't have the money to purchase a licence and I'm sure others are in the same boat.

The issue to which I was responding was whether Postgres JDBC drivers should 
support Java 1.4. How does your comment impinge on that?

My reasoning is that if a substantial body of customers uses Java 1.4, and 
there is some evidence that this is true, then Postgres JDBC drivers should be 
available for it.

The Extended support which potentially offers fixes, etc expires next year for 1.4 and a year after for 1.5. However I would use a similar argument as above, I don't have access to those commercial licences or any fixes, etc

And yet the quote you cite and purport to refute specifically promises 
"updates". How do you explain that?

> I understand that large enterprise setups are where 1.4 is being used which is why I posed the question, but I would echo the sentiments of Till in an earlier post, that the people with a requirement for 1.4 are unlikely to use a new version of the driver without substantial testing or a new version of the database, and if they do are likely to have paid support... but I maybe wrong?

And my answer is yes, we should support Java 1.4, for the reasons I stated and 
to which you have not spoken.
