Worked on the hyperledger-identus/cloud-agent repository to address a critical database migration issue affecting PostgreSQL compatibility. Focused on resolving a runtime error caused by the use of the reserved word 'format' in the presentation_definition schema, the developer implemented a fix by quoting the column name within migration scripts. This approach ensured that PostgreSQL could correctly interpret the schema, reducing deployment risk and improving reliability across different environments. Leveraging skills in SQL and database management, the work stabilized ongoing and future migrations, aligned with issue tracking processes, and helped prevent regressions related to reserved-word handling in PostgreSQL database schemas.
