Course schedule
1 Introduction and reminders
- PostgreSQL versions, SQL3 statement categories.
- Vocabulary of the relational model: bases, schemas, tablespaces.
- Interaction tools: psql, pgAdmin.
- Advanced types: numeric, strings, dates (DATE, TIMESTAMP, INTERVAL).
- PostgreSQL specific types : ARRAY, ENUM, OID.
- Operators and functions for arrays.
- Expression of constants.
- Introduction to transactions: start, end, SAVEPOINT.
2 PL/pgSQL language
- PL/pgSQL syntax and blocks.
- Variable declaration, %TYPE typing, name resolution.
- Control structures: IF, CASE, loops.
- Interaction with the database: update, consultation, FOUND variable.
- Cursors: declaration, open, FETCH, close.
- Stored procedures and functions.
- Parameter modes: IN, OUT, INOUT.
- Error diagnosis: EXCEPTION block, RAISE instruction.
Hands-on work
PL/pgSQL blocks, loops, cursors, stored procedures, error handling.
3 Triggers in PostgreSQL
- Types of triggers: instruction level versus line level.
- LMD events (INSERT, UPDATE, DELETE).
- Function executed by a trigger.
- Atomicity and consistency of operations.
- Use of triggers (audit, business automation).
Hands-on work
Creation of instruction-level and line-level triggers.
4 Transaction management
- Competition and consistency: deadlocks.
- Scenarios illustrating transaction management.
- Use of SAVEPOINT and sub-transactions.
- Transactions in PL/pgSQL: effect of errors, nested transactions.
- Cursors and transactions.
- Isolation levels: READ COMMITTED, REPEATABLE READ, SERIALIZABLE.
- Explicit table locking (LOCK TABLE).
- Line locks and associated locks.
Hands-on work
Simulate concurrency, isolation, line and table locking.
5 Objects and maintenance
- Databases and tablespaces: definition, role in storage.
- Schema management: creation, deletion, usage.
- Sequences, identity columns, calculated columns.
- pg_class catalog: meta-schema exploration.
- Dynamic schema modifications: columns, constraints.
- Indexes: types, creation, reorganization.
- Query analysis : EXPLAIN, ANALYZE.
- Maintenance: VACUUM, AUTOVACUUM, REINDEX.
- Partitioned tables: partitioning methods (range, list, hash).
- Temporary tables: uses and life cycle.
Hands-on work
Add/delete columns, indexes, partitioning, temporary tables, plan analysis.
6 Gestion des utilisateurs et configuration
- User creation and configuration.
- Roles and privileges: GRANT, REVOKE, object and schema rights.
- Isolate privileges between users.
- Starting and stopping PostgreSQL.
- Configuration files: postgresql.conf, pg_hba.conf.
- Customer authentication.
Hands-on work
Create users, manage privileges, modify configuration files.
