Consistent incrementer arrangement for PostgreSQL, DB2 and SAP HANA [SPR-16558]

[spring-projects-issues]

Juergen Hoeller opened SPR-16558 and commented

Spring's JDBC module provides several abstractions for provider-specific database mechanisms, in particular jdbc.support.incrementer. Over time, several inconsistencies have accumulated in the support for various databases there, in terms of class naming as well as database identification.

Let's use the 5.0.5 / 4.3.15 wrap-up (before entering the maintenance phase there) as an opportunity to revisit the support for PostgreSQL, DB2 (including its new LUW naming for the the Linux, Unix, Windows product) and SAP HANA ("HDB" as the primary JDBC database product name, and introducing a HanaSequenceMaxValueIncrementer).
