Feature/postgres sink

[le-vlad]

• [x] Batch inserts for a snapshot with COPY
• [x] Updates
• [x] Deletes
• [x] Inserts
• [x] Create table statements
• [ ] Alter table statement (Canceled)

In order to support deletions - we have to enable "Replica Identity Full for the table we are going to sync"

@imnotsurprised Do you think we should support alter table statements at this moment? Or should I skip them and implement in the next iteration?
