Postgres Core Schema Design
Use when starting a new PostgreSQL database, picking naming conventions, deciding multi-schema layout, or hardening search_path against SECURITY DEFINER injection. Prevents using SERIAL where IDENTITY is required (v10+), shipping a quoted-identifier mess ("camelCase" forces quotes everywhere), leaving public schema writable, and SECURITY DEFINER search_path hijack. Covers snake_case naming, IDENTITY vs SERIAL (v10+), multi-schema layout patterns, search_path semantics + injection risks, v15 public-schema default lockdown, multi-tenant via schema vs RLS decision tree. Keywords: schema design, naming convention, IDENTITY, GENERATED AS IDENTITY, SERIAL deprecated, search_path, SECURITY DEFINER, public schema, snake_case, multi-tenant, where should I put my tables, can I use camelCase, why does serial cause sequence issues, search path hijack, what schema layout, public schema permission denied, function ignoring search_path, identity vs serial which one
