Changes

=== CREATING SCHEMA -- ''PostgreSQLSchemaManager.java''===

:: 1- DATA TYPE: data types are changed in '''''<code> appendColumnType() </code>''''' based on each jdbc type's equivalent in PostgreSQL.

:::*[http://db.apache.org/ddlutils/databases/postgresql.html mapping JDBC data types to PostgreSQL data types]

</source>

:The implementation in '''''<code> crateTextTable() </code>''''' is removed for now (base class's version is being called).

:TODO To be checked if it's the case for PostgreSQL as well.

:The implementation in '''''<code> createIndex() </code>''''' is removed for now (base class's version is being called).

:TODO To be checked if it's the case for PostgreSQL as well.

:Note- If there was a complain for duplicate index name, a fully qualified name can be used. Just note that PostgreSQL doesn't like fully qualified name as <code>table.indexname</code> for indexes or triggers, instead a '_' can be used: <code>table_indexname</code>

:TODO To be checked if triggers are needed for PostgreSQL as well. It's not an abstract method in '''''SQLSchemaManager.java'''''.

: <code>'''''createTrigger()'''''</code> is added to '''''MySQLSchemaManager.java'''''
