Build

You can build the RPM / DEB packages for pg_drop_events using pig build:

pig build pkg pg_drop_events         # build RPM / DEB packages

Install

You can install pg_drop_events directly. First, make sure the PGDG and PIGSTY repositories are added and enabled:

pig repo add pgsql -u          # Add repo and update cache

Install the extension using pig or apt/yum/dnf:

Install

pig install pg_drop_events;          # Install for current active PG version

pig

pig ext install -y pg_drop_events -v 18  # PG 18
pig ext install -y pg_drop_events -v 17  # PG 17
pig ext install -y pg_drop_events -v 16  # PG 16
pig ext install -y pg_drop_events -v 15  # PG 15
pig ext install -y pg_drop_events -v 14  # PG 14

dnf

dnf install -y pg_drop_events_18       # PG 18
dnf install -y pg_drop_events_17       # PG 17
dnf install -y pg_drop_events_16       # PG 16
dnf install -y pg_drop_events_15       # PG 15
dnf install -y pg_drop_events_14       # PG 14

apt

apt install -y postgresql-18-pg-drop-events   # PG 18
apt install -y postgresql-17-pg-drop-events   # PG 17
apt install -y postgresql-16-pg-drop-events   # PG 16
apt install -y postgresql-15-pg-drop-events   # PG 15
apt install -y postgresql-14-pg-drop-events   # PG 14

Create Extension:

CREATE EXTENSION pg_drop_events CASCADE;  -- requires: plpgsql

Usage

pg_drop_events: logs transaction ids of drop table, drop column, drop materialized view statements

The pg_drop_events extension uses event triggers to automatically log details about DROP operations on tables, columns, and materialized views. The logged information can be used for point-in-time recovery (PITR) after accidental drops.

Tracked Operations

DROP TABLE
DROP COLUMN (via ALTER TABLE)
DROP MATERIALIZED VIEW

Logged Information

Column	Description
`pid`	Process identifier
`usename`	Database user who executed the command
`query`	The SQL statement
`xact_id`	Transaction identifier
`wal_position`	Write-ahead log position
`objid`	Object identifier
`object_name`	Fully qualified name of dropped object
`object_type`	Object classification (table, table column, etc.)
`xact_time`	Timestamp of the transaction

Example

CREATE EXTENSION pg_drop_events;

-- Drop a table
DROP TABLE t.t3;
-- NOTICE: table t.t3 dropped by transaction 1085.

-- Query the event log
SELECT * FROM pg_drop_events;

Point-in-Time Recovery

The logged data maps directly to PostgreSQL recovery parameters:

pg_drop_events column	Recovery parameter
`xact_id`	`recovery_target_xid`
`xact_time`	`recovery_target_time`
`wal_position`	`recovery_target_lsn`

Use these values in postgresql.conf or recovery.conf to restore the database to a point just before the accidental drop.
