Usage

omni_shmem: Shared Memory Management

The omni_shmem extension provides shared memory management facilities for PostgreSQL extensions within the Omnigres ecosystem.

It enables extensions to allocate and manage shared memory segments, providing the underlying infrastructure used by other Omnigres extensions that need cross-process shared state.
