PgAssistant is an open-source tool designed to assist developers in monitoring and optimizing PostgreSQL performance. However, users have noted the absence of visual documentation in the README, specifically screenshots that could enhance understanding of its interface and functionalities. Comparisons are being drawn between PgAssistant and other similar tools like PgHero and those available on GitLab, indicating a competitive landscape in the PostgreSQL optimization space. This suggests a need for PgAssistant to differentiate itself and provide comprehensive documentation to attract users.
