Gh 4627 Added DatabaseType POSTGRES for the product name EnterpriseDB

[sheelprabhakar]

Issue: [#4627] EnterpriseDB is an enterprise version of PostGres database, which identifies itself as EnterpriseDB. Added support for EnterpriseDB by adding the following condition in DatabaseType enum.

else if (StringUtils.hasText(databaseProductName) && databaseProductName.startsWith("EnterpriseDB")) {
			databaseProductName = "PostgreSQL";
		}

Since Enterprise version of PostGre requires license not able to add integration tests
