Hi!
Thanks for maintaining pgweb.
I noticed this issue when searching mailing lists. I did not test the change in the application, but I did test the logic in a local python console and I think it's right.
Commit message of the attached commit follows, explaining the issue:
Fix pagination link handling
If the total number of search results is divisible by the page size, the page count is mis-calculated and there's a link to an additional page of results, even though there are no more results and that page is empty.
See issue here: https://www.postgresql.org/search/?m=1&q=contrib&l=76&d=365&s=r&p=2
At the moment, this has 20 results but a link to a second page, which is empty with a label of "Results 21-20 of 20." Previous and Next works still work fine, but that second page does not really need to be there.
This changes the page count calculation to avoid this issue.
