Re: PSQL command line print speed

Is there a way to speed up the actual line-by-line display of the psql console in version 8.4?

Queries which perform in a few milliseconds through a driver (psycopg2 in this case) can take several seconds or minutes to complete in the console, seemingly just due to it printing lines at a very leisurely pace (in other words, this is not the delay caused by the query itself, often it starts printing almost instantly but spends a very long time just writing output). While overall application performance is unaffected, simple admin tasks and poking around the data take longer than I would like as a result. Is there any way to improve just the display/write performance in the console?

try to play with used format

probably unalign format will be faster

postgres=# \pset format unaligned 

Output format is unaligned.

Pavel

 

Thanks for any insight,
