pgcheck is a one-click tool to get the running status of PostgreSQL, including stream replication/lock/wait events/partition/index/relation,etc., which makes the operation and maintenance more efficient.
The current supported versions include 11, 12, 13, 14, and 15. Other versions may be a little incompatible, and some of them report errors, but most of them can also be used.
[postgres@xiongcc pgcheck_tool]$ ./pgcheck

./pgcheck dbstatus database : list all database status and statistics
./pgcheck index_bloat database : index bloat information (estimated value)
./pgcheck index_duplicate database : index duplicate information
./pgcheck index_low database : index low efficiency information
./pgcheck index_state database : index detail information
./pgcheck lock database : lock wait queue and lock wait state
./pgcheck checkpoint database : background and checkpointer state
./pgcheck freeze database : database transaction id consuming state
./pgcheck replication database : streaming replication (physical) state
./pgcheck connections database : database connections and current query
./pgcheck long_transaction database : long transaction detail
./pgcheck relation_bloat database : relation bloat information (estimated value)
./pgcheck vacuum_state database : current vacuum progress information
./pgcheck index_create database : index create progress information
./pgcheck wal_archive database : wal archive progress information
./pgcheck wal_generate database wal_path : wal generate speed (you should provide extra wal directory)
./pgcheck wait_event database : wait event and wait event type

Email: xiongcc_1994@126.com/xiongcc_1994@outlool.com. Wechat: _xiongccCurrently supported features include：
- View the table status information in the specified schema
- View the information of all toast tables in the specified schema and the toast information of a specified table
- View the overall status information of the database, which will be different in different versions (please specify the exact version of the psql environment variable, because the system views of different versions will be different, and the judgment is made in the code, otherwise an error may be reported)
- View index bloat ratio/redundant index/inefficient index/index overall information
- View index information
- View checkpoint and background writer process status
- View age
- View streaming replication status
- View the number of connections and queries currently being allowed
- View long transactions
- View table bloat, table bloat depends on statistical information, so in order to be more accurate, it is best to do an analysis before doing it, this query will take a little time
- Check the index creation progress, only supported in versions after 12, and the previous version will prompt that the view does not exist and exit
- View WAL archive status
- View WAL generation speed
- View waiting time
- View partition table information, including native partitions and inherited partitions
- View objects owned by a user, and membership
The default port used is 5432. If there are multiple instances on the server, you can specify environment variables before use, such as export PGPORT=5433。
