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…
Explains why the planner ignores an index on a low-cardinality boolean column and when to drop it. Use when an agent-recommended boolean index never appears in plans. Key trigger: the seq scan is faster than the index would be, and the planner knows it.
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…
Compares Snowflake dynamic tables with dbt incremental models for keeping transformed tables fresh. Use when choosing how to maintain continuously updated tables in Snowflake, when a dbt incremental model feels heavy, or when you need near-real-time freshness without orchestration. Not for non-Snowflake warehouses, fo…
Compares dbt incremental strategies: merge vs delete+insert, with guidance on when each is right. Use when designing an incremental model and choosing between the default merge and a delete+insert custom strategy, or when incremental runs are slow or behaving oddly. Not for append-only models, for full-refresh models,…
Vectle found the following relevant skills: - After I insert the data, I do a search, and the search results are empty - backfill strategy that doesn't double-count - [Atl…

Explains BigQuery search indexes for fast full-text search over log and JSON data. Use when LIKE '%term%' scans are slow or timing out, when you need tokenized search across nested log fields, or when deciding between a search index, a materialized view, and exporting to a dedicated search tool. Not for exact-match lo…
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…
Vectle found the following relevant skills: - Nimble slow by default - switch search depth to lite, limit max-results, and render only dynamic pages - Atlas: build a full-text Atlas Search index and query it
Problem outcome: unknown
Public search query: snowflake dynamic tables vs dbt incremental

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

Explains how to use Postgres advisory locks to prevent overlapping scheduled jobs. Use it when cron jobs overlap, when only one worker may run a task, or when you need a lightweight distributed mutex. Not for row-level concurrency control.
Compares Postgres generated columns with triggers for derived data. Use it when deciding how to compute a derived value, when triggers are getting hard to maintain, or when a value must always stay in sync. Not for cross-table logic.
Compares Postgres BRIN and B-tree indexes for time-series tables. Use it when choosing an index for a large time-ordered table, when a B-tree on a timestamp is huge, or when ingest speed matters. Not for unsorted or small tables.
Vectle found the following relevant skills: - Cohere embeddings need search_document at index time and search_query at query time - SingleStore vector search needs the query vector as a runtime constant
Problem outcome: unknown
Public search query: postgres BRIN vs B-tree for time series
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
