+# PostgreSQL Source Installation Scripts
+
+These shell scripts build PostgreSQL from source and install PostgreSQL extensions into a versioned prefix:
+
+```text
+/app/postgres/rdbms/<postgresql-version>
+```
+
+The scripts use strict Bash error handling and require a working compiler and build environment. Sources are downloaded from the PostgreSQL FTP site and GitHub repositories.
+
+## Install everything
+
+Run the orchestrator with the PostgreSQL version to install:
+
+```bash
+./install_postgresql_extensions.sh 18.6
+```
+
+The orchestrator runs the installers in this order:
+
+1. PostgreSQL
+2. pg_cron
+3. TimescaleDB
+4. pgAudit
+5. set_user
+6. pg_stat_statements
+7. pg_repack
+8. pg_stat_monitor
+
+After a successful run, the orchestrator:
+
+- Optionally updates `shared_preload_libraries` when `CONFIG_FILE` is set.
+- Prints the installed PostgreSQL and extension versions.
+- Creates `postgresql-<version>-engine.tar.gz` in the directory from which the command was launched.
+- Writes the complete process log to `postgresql-<version>-process.log` in that same directory.
+
+## Individual installers
+
+Each component can also be installed independently. The PostgreSQL installation must already exist before running an extension installer.
+
+```bash
+./install_postgresql.sh 18.6
+./install_pg_cron.sh 18.6
+./install_timescaledb.sh 18.6
+./install_pgaudit.sh 18.6
+./install_set_user.sh 18.6
+./install_pg_stat_statements.sh 18.6
+./install_pg_repack.sh 18.6
+./install_pg_stat_monitor.sh 18.6
+```
+
+`install_postgresql.sh` recreates both the staging directory and the versioned PostgreSQL prefix before downloading sources. Extension installers recreate only the staging directory and preserve the PostgreSQL prefix.
+
+## Script descriptions
+
+### `install_postgresql_extensions.sh`
+
+All-in-one entry point. It invokes every installer, applies optional configuration changes, prints a product summary, writes a process log, and packages the installed PostgreSQL prefix.
+
+### `install_postgresql.sh`
+
+Downloads, configures, builds, and installs PostgreSQL. The build uses:
+
+```text
+--with-ssl=openssl
+--with-lz4
+```
+
+### `install_pg_cron.sh`
+
+Builds and installs `pg_cron` against the selected PostgreSQL installation.
+
+### `install_timescaledb.sh`
+
+Bootstraps and builds TimescaleDB with CMake, installing it into the selected PostgreSQL prefix.
+
+### `install_pgaudit.sh`
+
+Builds and installs pgAudit using PostgreSQL PGXS. It selects a tag matching the PostgreSQL major version when possible.
+
+### `install_set_user.sh`
+
+Builds and installs the `set_user` extension using the selected PostgreSQL `pg_config`.
+
+### `install_pg_stat_statements.sh`
+
+Downloads the matching PostgreSQL source tree and builds `pg_stat_statements` from `contrib` using PGXS.
+
+### `install_pg_repack.sh`
+
+Builds and installs the `pg_repack` extension and its `pg_repack` command-line utility.
+
+### `install_pg_stat_monitor.sh`
+
+Builds and installs Percona's `pg_stat_monitor` extension.
+
+### `install_common.sh`
+
+Shared helper functions used by the installers, including:
+
+- Required-command checks
+- PostgreSQL version validation
+- GitHub release/tag lookup
+- Source download and extraction
+- Staging-directory reset
+- PostgreSQL-prefix validation
+
+## Configuration
+
+The following environment variables can override defaults:
+
+| Variable | Default | Purpose |
+| --- | --- | --- |
+| `POSTGRES_ROOT` | `/app/postgres/rdbms` | Root directory for versioned PostgreSQL installations |
+| `STAGING_DIR` | `/app/staging_area/copilot/tmp` | Temporary source and build directory |
+| `JOBS` | `nproc` result | Parallel build job count |
+| `CONFIG_FILE` | unset | PostgreSQL configuration file to update |
+| `PG_CRON_TAG` | Latest compatible release/tag | pg_cron source tag |
+| `TIMESCALEDB_TAG` | Latest release/tag | TimescaleDB source tag |
+| `PGAUDIT_TAG` | PostgreSQL-major-compatible tag | pgAudit source tag |
+| `SET_USER_TAG` | Latest release/tag | set_user source tag |
+| `PG_REPACK_TAG` | Latest release/tag | pg_repack source tag |
+| `PG_STAT_MONITOR_TAG` | Latest release/tag | pg_stat_monitor source tag |
+
+Repository variables can also be overridden when using a custom mirror:
+
+```bash
+PG_CRON_REPOSITORY=owner/repository
+TIMESCALEDB_REPOSITORY=owner/repository
+PGAUDIT_REPOSITORY=owner/repository
+SET_USER_REPOSITORY=owner/repository
+PG_REPACK_REPOSITORY=owner/repository
+PG_STAT_MONITOR_REPOSITORY=owner/repository
+```
+
+Example:
+
+```bash
+JOBS=8 \
+PG_CRON_TAG=v1.6.5 \
+TIMESCALEDB_TAG=2.19.3 \
+PGAUDIT_TAG=17.1 \
+SET_USER_TAG=REL4_2_0 \
+./install_postgresql_extensions.sh 17.11
+```
+
+When `CONFIG_FILE` is supplied, the orchestrator adds the extensions that require server startup loading:
+
+```conf
+shared_preload_libraries = 'pg_cron,timescaledb,pgaudit,pg_stat_statements,pg_stat_monitor'
+```
+
+`pg_repack` and `set_user` do not require `shared_preload_libraries`. `pg_stat_activity` is a PostgreSQL system view and is not installed as an extension.
+
+## Prerequisites
+
+The scripts check for the tools needed by each build. The complete procedure requires:
+
+- Bash
+- `curl`
+- `tar`
+- `make`
+- `gcc`
+- `cmake`
+- `python3` when `CONFIG_FILE` is used
+- Standard PostgreSQL build dependencies, including OpenSSL and LZ4 development libraries
+
+## Validation
+
+Validate all shell scripts:
+
+```bash
+for script in install_*.sh; do
+  bash -n "$script"
+done
+```
+
+Check an installed PostgreSQL version:
+
+```bash
+/app/postgres/rdbms/18.6/bin/postgres --version
+/app/postgres/rdbms/18.6/bin/pg_config --version
+```
+
+Check installed extension files:
+
+```bash
+ls \
+  /app/postgres/rdbms/18.6/lib/pg_cron.so \
+  /app/postgres/rdbms/18.6/lib/timescaledb.so \
+  /app/postgres/rdbms/18.6/lib/pgaudit.so \
+  /app/postgres/rdbms/18.6/lib/set_user.so \
+  /app/postgres/rdbms/18.6/lib/pg_stat_monitor.so
+```
+
+The extension SQL objects still need to be created in each target database with PostgreSQL's `CREATE EXTENSION` command.
