Description

I'm using org.testcontainers:postgresql:1.11.3 dependency and it has no Automatic-Module-Name manifest attribute. It leads to module name conflict, as module name for the dependency is just postgres.

Please add this attribute to all published artifacts. For postgresql it can be smth like testcontainers.postgresql.

Research direction
The issue requests adding an Automatic Module Name attribute to META INF/MANIFEST.MF for all published artifacts (e.g., testcontainers.postgresql). To implement, locate the build configuration files (pom.xml or build.gradle) for each module and add the manifest entry. For Maven, use the maven jar plugin with <manifestEntries><Automatic Module Name>...</Automatic Module Name></manifestEntries>. For Gradle, use the jar task with manifest.attributes. The PostgreSQL module is specifically mentioned; check the existing module structure in the repository.
