Postgres MCP Pro Server for Database Analysis and Tuning

SUSPICIOUS due to transitive skill installation and source/distribution mismatch: users are told the skill is sourced from `crystaldba/postgres-mcp`, but the actual install target is the separate `agentskillexchange/skills` repo. That is a medium supply-chain risk and trust-chain issue, but there is no direct evidence in the provided text of credential theft, covert exfiltration, or behavior fundamentally incompatible with a PostgreSQL analysis skill.
