Will Altering and Modifying tables during backup result in a corrupted server after the restore?

Hi All,

We are trying this scenario:
Here are the steps being done:

1. Creating a big table. Identify the physical file on the disk.

1. While backup process is backing up a file associated with the table - update the rows , add a column.
2. Restore the server with transaction logs

We are backing up (copying) the entire postgres data directory. The database/table file being backed up (copied), is modified by running alter/update queries on the table.
When we restore the copied data directory and replay/apply the transaction logs, will the server be restored to an healthy state?
(The files modified during backup can be corrupted, will this affect the restore?)

Thanks,
Yashwanth
