pg_dump - Text Format:
# Simple full backup
pg_dump -h localhost -U postgres -F p database_name > backup.sql
# With compression
pg_dump -h localhost -U postgres -F p database_name | gzip > backup.sql.gz
# Backup with verbose output
pg_dump -h localhost -U postgres -F p -v database_name > backup.sql 2>&1
# Exclude specific tables
pg_dump -h localhost -U postgres database_name \
--exclude-table=temp_* --exclude-table=logs > backup.sql
