Not sure if such case would corrup the backup, but I won't make a backup just by copying the data directory.
Use pg_basebackup instead, it's safer

Subject: 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
modifiedby 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
healthystate?
(The files modified during backup can be corrupted, will this affect the restore?)
Thanks,
Yashwanth
