I have several users accessing PostgreSQL database managed through pgAdmin. The database consists of a table with several columns and rows. I want to grant permission to certain users to write/edit certain certain rows based on the value of a certain cell i.e., if cell value = x than user 123 has edit rights. From what I have understood, the Grant Wizard grants access to the entire table. Is there anyway be more granular in granting access/assigning roles?
