>From what I've tried we will have to add: postgresql-9.0-801.jdbc4.jar to the WEB-INF/lib for postgres For other drivers similar connectors have to be added to the libraries.
For the datatypes, liquibase 2.0.0 has automatic conversions <http://forum.liquibase.org/topic/postgres-with-type-longtext-and-best-practice-for-supporting-multiple-database>for common types between databases. There are also extensions that can be written for our mods. --- Regards, Saptarshi PURKAYASTHA My Tech Blog: http://sunnytalkstech.blogspot.com You Live by CHOICE, Not by CHANCE On 10 August 2011 22:31, Friedman, Roger (CDC/CGH/DGHA) (CTR) <[email protected]>wrote: > Seems like there shouldn't be a dependency at all, the code should just > try to instantiate the appropriate driver.
