Re: WIP: Collecting statistics on CSV file data

Hi,

I revised the patch according to Hanada-san's comments. Attached is the
updated version of the patch.

Changes:

  * pull up of logging "analyzing foo.bar"
  * new vac_update_relstats always called
  * tab-completion in psql
  * add "foreign tables are not analyzed automatically..." to 23.1.3
Updating Planner Statistics
  * some other modifications

Best regards,
