The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/15/citext.html Description:
On https://www.postgresql.org/docs/current/citext.html in "F.10.2. How to Use It", it says "here's a simple example of usage" and begins by creating a table with a `CITEXT` column. For seasoned PostgreSQL users, it may be obvious that before running such an example, one must `CREATE EXTENSION IF NOT EXISTS citext;`, but if a newer user is told "use citext for this column" and given a link to this page, nothing tells them how to enable it. I suggest adding this instruction somewhere on this page, either in its own section like "How to Enable It", or at the start of the "simple example", or even at the end of the sentence near the top: "It can be installed by non-superusers who have CREATE privilege on the current database by running `CREATE EXTENSION IF NOT EXISTS citext;`."
