Progress bar is run-time SQL-query progress indicator. Function progress_bar(pid) extracts the current query state from backend with specified 'pid'. Then gets the numerical values of the actual rows and total rows and count progress for the whole query tree. Function returns numeric value from 0 to 1 describing the measure of query fulfillment. This function can be used to be embedded in the PostgreSQL GUI. To intuitively track progress without using a graphical client, you can use the additionally implemented function progress_bar_visual(pid, delay). It prints state every period specified by 'delay' (in seconds).
The progress value is equal to the actual_rows ratio to plan_rows as a percentage. Or 100% if actual_rows > plan_rows. The progress value is added for each node in the current_loop. The progress value is added to the message taking into account the format (TEXT, XML, JSON, YAML) and provided that the parameter costs = true. Tags: pg_query_state
