Postgres -> Snowflake silent failure with manual schema change approval

### Connector Name

source-postgres

### Connector Version

v3.8.0-rc.11

### What step the error happened?

During the sync

### Relevant information

All of our Snowflake destination conections have been set to `Approve all changes myself` for the past few years. The behavior we have come to expect is:
- if a postgres column is added, the existing columns in the stream still sync
- if a postgres column is deleted, the remaining columns in the stream still sync
- all changes are applied when I manually update the schema

However, as of last week we started to have scheduled Airbyte runs have streams with changes silently fail when columns were removed. These were not breaking changes by Airbytes definitions. This meant that we did not receive any emails and assumed all systems were live; however our downstream users were missing data for almost a week.
