From: Fernando Oliveira

Subject: Fernando Oliveira's Postgress SQL Server Data Connector as a single
commit. * Added PostGreSQL support * Added MySQL/MySQLXGroupData.cs *
PostgreSQL data access implementation * PostgreSQL dll binarie and
RegionStore.migrations * Migrations Scripts from MSSQL to POSTGRES * Postgres
SQL Type fixes * Postgres SQL Connection string * Data type issues * more
fixes * tests and +tests * UUID x string - FIGHT! * Fixed PG types to
internal csharp types * More data type fix (PostgreSQL fields are case
sensitive) :( * more field case sensitive fixes * changed the migration files
to be case sensitive for fields. * fixed fields case * finished converting,
now search for hidden bugs. * some more fixes * bool type fixed * more case
fixes; * creatorID case fixed * case fields fixed * fixed default now() for
TMStamp fields with don't allow nulls. * fix case sensitve for Region name
and Estate name * fixed case for names for search * fix class name Error *
Bug fixed on select and migrations * Un-Reverting my change due to Postgres
issue with the ILIKE function * Fixed some issued for Diva Distro * Fixes for
integration with Diva Distro * Added System.Core to prebuild.xml for PG
project * Configured to make DIff for Push to OpenSim Project * Diffs only to
PostgreSQL mods.
