-connection string  docker exec -it timescale_db-bo3nov2ija7g8wn9b1g2paxs-210508774107 psql -U postgres -d tracksolid_db
+## Database Access
+
+The TimescaleDB container name includes a Coolify-generated suffix that changes on every redeploy. Use the shell function below instead of hardcoding the container name.
+
+### Recommended: add to `~/.zshrc` on the server
+
+```bash
+# Auto-resolves current TimescaleDB container — survives Coolify redeployments
+tsdb() {
+  local container
+  container=$(docker ps --filter "name=timescale_db" --format "{{.Names}}" | head -1)
+  if [[ -z "$container" ]]; then
+    echo "ERROR: no running timescale_db container found" >&2
+    return 1
+  fi
+  docker exec -it "$container" psql -U postgres -d tracksolid_db "$@"
+}
+```
+
+After adding it: `source ~/.zshrc`
+
+**Usage:**
+
+```bash
+tsdb                                                  # open interactive psql prompt
+tsdb -c "\dt tracksolid.*"                            # list all tracksolid tables
+tsdb -c "SELECT COUNT(*) FROM tracksolid.trips;"      # run a single query
+tsdb -c "SELECT dwh_gold.refresh_daily_metrics(CURRENT_DATE - 1);"  # run nightly ETL
+```
+
+### One-liner (for scripts and migrations)
+
+```bash
+TS_DB=$(docker ps --filter "name=timescale_db" --format "{{.Names}}" | head -1)
+docker exec -i "$TS_DB" psql -U postgres -d tracksolid_db < migration.sql
+```
+
+> Use `-i` (not `-it`) when piping SQL files — the `-t` TTY flag conflicts with stdin redirection.
+
+### If multiple TimescaleDB containers are running
+
+Filter by Coolify label instead of name to target a specific instance:
+
+```bash
+# Inspect available labels first
+docker inspect $(docker ps --filter "name=timescale_db" --format "{{.Names}}" | head -1) \
+  --format '{{json .Config.Labels}}' | jq .
+
+# Then filter by a stable label, e.g.:
+TS_DB=$(docker ps --filter "label=coolify.name=timescale_db" --format "{{.Names}}" | head -1)
+```
