Hello,
Thank You for the reply. I managed to delete the row the way below:
1. Using EMS Manager for PostgreSQL I selected all the rows except the corrupted one.
2. Extracted the data to INSERT script
3. SET zero_damaged_pages TO true; VACUUM FULL table;
4. DROP/CREATE
5. INSERT script without the corrupted row
6. INSERT script for the missing row created with EMS from the las uncorrupted data folder
Everything went as predicted and the table is ok now.

sort of corruption this is, you might be able to delete the damaged row
with
DELETE FROM table WHERE ctid = '...';
