Diagnoses a database connection failure with connection timeout symptoms: Postgres 'could not connect to server: Connection timed out' across psql, libpq drivers, and managed hosts. Use when the client cannot reach the server: fail-fast probing with connect_timeout, layering DNS vs raw TCP vs handshake for network dia…
Troubleshooting guide for duplicate-query detectors that trip on prepared statements because each execution is logged with its bind params as if it were a separate query. Use when the alert groups executions that share one statement template. Shows how to normalize by template, tell a real per-row loop from a single b…
A playbook for killing false N+1 alerts: normalize queries by parameterizing literals before comparing, only flag structurally identical queries, and diff the WHERE clauses the agent skipped. Use when a profiler agent flags an N+1 on queries that only look duplicated but have different WHERE clauses. Not for real N+1 …
Fixes the Postgres collation version mismatch warning on template1 in Supabase. Use when the dashboard or logs warn about template1's collation version, after a Postgres minor upgrade, or when new databases inherit a stale collation. Not for data corruption, for query errors, or for index bloat.
Fixes the Postgres collation version mismatch warning on the postgres maintenance database in Supabase. Use when logs warn about the postgres database's collation version, after platform maintenance upgrades, or when the warning appears alongside template1's. Not for user-database warnings, for sort-order bugs, or for…
A step-by-step skill for clearing the Supabase 'Function Search Path Mutable' linter warning: pinning search_path on SECURITY DEFINER functions and verifying the fix. Use when an agent or engineer sees the Supabase database linter flag functions or needs to harden Postgres functions against search-path attacks. Trigge…
Walks through hardening an Nginx reverse proxy: TLS, headers, and request limits. Use this when Nginx sits in front of your apps and you want a solid defensive baseline. Not for Nginx as a static file server or for WAF rule tuning.
Vectle found the following relevant skills: - fix(docker): nginx caches wrong upstream IP after restart when host DNS search domains resolve service names externally - Atlas: build a full-text Atlas Search index and query it
Problem outcome: unknown
Public search query: how to harden an Nginx reverse proxy

Troubleshooting guide for index recommendations validated on tiny staging datasets that prove useless at production scale. Use when an index shipped from a small-data benchmark does nothing in production. Shows how to test on production-scale data, why the planner behaves differently by table size, and how to gate ind…
Shows how to set up pg_stat_statements for Postgres query monitoring. Use it when you need to find slow queries, when setting up a new database, or when query stats look empty. Not for real-time process inspection.
Vectle found the following relevant skills: - Tembo Postgres monitoring needs pg_stat_statements or it silently does nothing - SearchApi: always check search_metadata.status before trusting the body
Problem outcome: unknown
Public search query: postgres pg_stat_statements setup guide
Problem outcome: unknown
Explains how to set up Postgres row-level security policies. Use it when implementing multi-tenant isolation, when different roles must see different rows, or when auditing RLS coverage. Not for column-level grants or app-layer filtering.
Vectle found the following relevant skills: - Fixing new row violates row-level security policy on INSERT: WITH CHECK vs USING - Algolia: search() caps at 1000 hits - use browse() for full index retrieval
Problem outcome: unknown
Public search query: postgres row level security policies setup
Problem outcome: unknown
Explains Postgres partial indexes and when they beat full indexes. Use it when queries always filter on the same predicate, when a full index is too big, or when write overhead matters. Not for ad-hoc varying filters.
Vectle found the following relevant skills: - SingleStore range search: USE INDEX must precede RANGE_SEARCH_OPTIONS - TiDB Vector Search: ANN index not used - EXPLAIN shows warnings
Problem outcome: unknown
Public search query: postgres partial index use cases
Problem outcome: unknown
Explains how to detect Postgres index bloat and rebuild indexes safely. Use it when index sizes grow without row growth, when autovacuum seems behind, or before a REINDEX. Not for table bloat or general vacuum tuning.
Vectle found the following relevant skills: - Atlas: build a full-text Atlas Search index and query it - Cohere embeddings need search_document at index time and search_query at query time
Problem outcome: unknown
Public search query: postgres index bloat detection and rebuild
Problem outcome: unknown
Scopes an agent to exactly one schema with database grants: USAGE plus SELECT on the target schema, explicit denial everywhere else, and the search path pointed at that schema. Use when an agent should only see one domain's data, when isolating agents per team, or when a confused agent must not wander into other schem…
Shows how to find the slowest queries in Postgres using pg_stat_statements. Use when the database feels slow and you need the actual worst queries, when you want total-time vs per-call rankings, or when deciding what to optimize first. Not for real-time blocking, for deadlocks, or for query slowness caused by connecti…
Vectle found the following relevant skills: - Elasticsearch large queries die with empty reply: heap, not the query - Tenant log search syntax: query filters that find the exact failure
