pgpool命令

查询锁：

SELECT

locked.pid AS locked_pid,

locker.pid AS locker_pid,

locked_act.usename AS locked_user,

locker_act.usename AS locker_user,

locked.virtualtransaction,

locked.transactionid,

relname

FROM

pg_locks locked

LEFT OUTER JOIN pg_class ON (locked.relation = pg_class.oid),

pg_locks locker,

pg_stat_activity locked_act,

pg_stat_activity locker_act

WHERE

locker.granted=true AND

locked.granted=false AND

locked.pid=locked_act.pid AND

locker.pid=locker_act.pid AND

locked.relation=locker.relation;

---------------------

select * from pg_stat_activity aa,

(

select a.locktype,a.database,a.pid,a.mode,a.relation,b.relname from pg_locks a join pg_class b on a.relation=b.oid

where upper(b.relname)=FX_WDSJ_DSZH

) bb

where aa.pid=bb.pid

and aa.waiting=t

–查询是否锁表了

select pid from pg_locks where relation=(select oid from pg_class where relname=表);

tb_cyplate_localitycheck

查询proc：

select proname --, prosrc

from pg_proc where LOWER(prosrc) like %join% and CHAR_LENGTH(prosrc) ##  100;

查询连接：

SELECT * FROM pg_stat_activity

查询正在执行的语句：

select * from pg_stat_activity where waiting=t;

kill pid：

select pg_cancel_backend(16023);

select  pg_terminate_backend(16023);

查询备机延迟：

select now()-pg_last_xact_replay_timestamp()

查询备机：

select * from pg_stat_replication;

/opt/postgres/9.3/bin/psql -U postgres -p 5432 -c "select * from pg_stat_replication;"

查询语句log：

select * from pg_stat_statements

where query like %tttt%;

清除语句log：

SELECT pg_stat_statements_reset();

显示同步备机名：

show synchronous_standby_names

pgagent:

/opt/pgagent/bin/pgagent hostaddr=localhost dbname=postgres user=postgres

pgpool:

/opt/postgres/9.3/bin/psql -U postgres -p 9999 -c "show pool_nodes;"
