hello @TianT1209

thank you for reporting this issue. Based on the logs you provided, this appears to be a PostgreSQL/pgvector initialization problem rather than just a resource issue.

the errors show:

• postgres is needed by initdb but was not found
• Cannot allocate memory
• popen failure

this could be caused by several factors and steps to fix:

1. clean restart the database:

   docker-compose down -v
   docker-compose up -d

2. check system resources:
   please verify system requirements from README.

3. check Docker resources:
   ensure Docker has sufficient memory allocated (at least 4GB recommended).

please provide additional information:

• what OS and CPU architecture are you using?
• what are your server hardware specifications (RAM, CPU)?
• docker version: docker --version
• docker Compose version: docker-compose --version
• full logs from pgvector container: docker logs pgvector

let me know the results of the clean restart and your system information
