migrating-oracle-to-postgres-stored-procedures
Migrates Oracle PL/SQL stored procedures to PostgreSQL PL/pgSQL. Translates Oracle-specific syntax, preserves method signatures and type-anchored parameters, leverages orafce where appropriate, and applies explicit collation mapping (COLLATE "C" only when appropriate, locale collations when required). Use when converting Oracle stored procedures or functions to PostgreSQL equivalents during a database migration.

Migrating Stored Procedures from Oracle to PostgreSQL
Translate Oracle PL/SQL stored procedures and functions to PostgreSQL PL/pgSQL equivalents.
Workflow
Progress:
- [ ] Step 1: Read the Oracle source procedure
- [ ] Step 2: Translate to PostgreSQL PL/pgSQL
- [ ] Step 3: Write the migrated procedure to Postgres output directory
Step 1: Read the Oracle source procedure
Read the Oracle stored procedure from .github/oracle-to-postgres-migration/DDL/Oracle/Procedures and Functions/. Consult the Oracle table/view definitions at .github/oracle-to-postgres-migration/DDL/Oracle/Tables and Views/ for type resolution.
Step 2: Translate to PostgreSQL PL/pgSQL
Apply these translation rules:
- Translate all Oracle-specific syntax to PostgreSQL equivalents.
- Preserve original functionality and control flow logic.
- Keep type-anchored input parameters (e.g.,
PARAM_NAME IN table_name.column_name%TYPE). - Use explicit types (
NUMERIC,VARCHAR,INTEGER) for output parameters passed to other procedures — do not type-anchor these. - Do not alter method signatures.
- Do not prefix object names with schema names unless already present in the Oracle source.
- Leave exception handling and rollback logic unchanged.
- Do not generate
COMMENTorGRANTstatements. - Apply collation intentionally when ordering text:
- Use
COLLATE "C"only when Oracle-compatible binary ordering is required and no other sort order is specified. - If Oracle used explicit linguistic sorting (for example
NLS_SORT = French), map to an explicit PostgreSQL locale collation instead of"C". - Use
SELECT collname, collprovider, collcollate, collctype FROM pg_collation ORDER BY collname;to discover collations in the target environment.
- Use
- Treat
UNION ALLas a review checkpoint. Validate plan quality per branch and restructure if combined-branch planning causes regressions (for example, unexpected sequential scans on large tables). - Leverage the
orafceextension when it improves clarity or fidelity.
Consult the PostgreSQL table/view definitions at .github/oracle-to-postgres-migration/DDL/Postgres/{ProjectName}/Tables and Views/ for target schema details.
Step 3: Write the migrated procedure to Postgres output directory
Place each migrated procedure in its own file under .github/oracle-to-postgres-migration/DDL/Postgres/{ProjectName}/Procedures and Functions/{PACKAGE_NAME_IF_APPLICABLE}/. One procedure per file.
{ProjectName}is the project's assembly/folder name with spaces normalized to-(e.g.MyApp.DataAccess). This matches the path used by the agent and other migration skills.

Popular data & databases skills
supabase-postgres-best-practices
supabase/agent-skills
Postgres best practices maintained by Supabase, for Postgres running anywhere. Load this skill BEFORE writing or changing anything that lives in a Postgres database: creating or altering tables and columns (including choosing column types), schema design, migrations and declarative schema files, RLS policies and the tests that verify them, indexes, triggers, database functions, queues and scheduled jobs (pgcron, pgmq), vector/semantic search (pgvector), and restoring dumps (pgrestore) or importing data. Also load it when diagnosing slow queries, high CPU, timeouts, EXPLAIN plans, connection exhaustion, locking, bloat, or rows visible to the wrong user or tenant. This is not just a performance guide — schema, migration, security, and SQL authoring tasks need these rules too, even for a one-column change or a single query.
