PostgreSQL writes its WAL (write-ahead log) record into the buffers, and then these buffers are flushed to disk. The default size of the buffer, defined by wal_buffers, is 16MB, but if you have a number of concurrent connections, then a higher value can give better performance...
Auto_explain (**) A Postgres extension that logs execution plans of slow queries automatically. PostgreSQL pgBadger Very popular Postgres log file analyzer with a graphical output. Helps find long-running queries, demanding workloads, etc. PostgreSQL Disaster Recovery and High Availabili...
might be to have a direclty indexable column that states a queue is elegable to go and search based upon that instead of deriving this property. That may add too much extra logic for maintaining that value though so you'd have to assess that against the savings made in queries like ...
I have a regular case where I run many Postgres queries within a do/begin/end block DO $$ BEGIN <queries> END $$; In some cases, the databases and queries run a little bit slow and we need visibility to estimate how long the transaction will take and see any problems along ...
Built-in platform and CLI tools help you understand system performance at a glance, with key metrics like CPU, IOPS, connections, and storage resources. Postgres Insights enhances database performance with automated assistance for monitoring cache hit ratio, index hits, and slow queries. ...
If you want to identify slow queries, than the method is to use log_min_duration_statement setting (in postgresql.conf or set per-database with ALTER DATABASE SET). When you logged the data, you can then use grep or some specialized tools - like pgFouine or my own analyzer - which...
