• Enhancement/New feature (adds functionality without impacting existing logic)
• Breaking change (fix or feature that would cause existing functionality to change)

Description

Fix Postgresql auto increment details. Extracted code from ColumnSnapshotGenerator into new class AutoIncrementSequencesCache, and by doing this get rid of a deprecated method usage and creates a standard way to implement new sequence queries.

The AutoIncrementSequencesCache will run a query once against the database and store a cache of all sequences that are related to auto increment fields. To add support to anotehr database , a new query needs to be created returing the same 5 fields that are provided by the existing queries.

Things to be aware of

• Fixes Postgres autoIncrementInformation in snapshot is not correct #2867 .
• This change breaks Postgresql addAutoIncrement tests on test-harness, so PR Add autoincrement startsWith/increment validations to postgresql tests. liquibase-test-harness#377 needs to be merged together with this one to ensure it passes.

Things to worry about

• None

PR fixes a bug where Liquibase did not capture the start value and increment by parameters for Postgres autoincrement columns. The bug fixes the underlying issue in snapshot as well as snapshot-based commands like generate-changelog and diff-changelog.

• Code refactored to be more readable.
• Associated liquibase-test-harness PR to add automated test case PR
• No additional testing required.
