Feature/postgres sink

[le-vlad]

• Batch inserts for a snapshot with COPY
• Updates
• Deletes
• Inserts
• 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?
