- DatabaseMetaData.supportsAlterTableWithDropColumn() as psql doesn't
|
||||
support dropping of individual columns
|
||||
- Merged in some last patches. Only 1 left, which may not be compatible
|
||||
with jdbc1
|
||||
- Merged in my old retepsql project. Makefile now includes it.

- Removed the DriverClass kludge. Now the org.postgresql.Driver class
|

is compiled from a template file, and now has both the connection
|

class (ie jdbc1/jdbc2) and the current version's from Makefile.global

||||
* It writes jdbc1 to stdout for the 1.1.x VM.
|
||||
*
|
||||
* For 1.2 or 1.3, it checks for the existence of the javax.sql.DataSource
|
||||
* interface, and if found writes enterprise to stdout. If the interface
|
||||
* is not found, it writes jdbc2 to stdout.
|
||||
*
|
||||
* PS: It also looks for the existence of java.lang.Byte which appeared in
|
||||
* JDK1.1.0 incase java.vm.version is not heeded by some JVM's.
|
||||
*
|
||||
* If it can't work it out, it writes huho to stdout.
|
||||
*
|
||||
* The make file uses the written results to determine which rule to run.
|
||||
*
|
||||
* Bugs: This needs thorough testing.
