If anybody's up for the job, that'd be great. I've looked at 9.4's postgresql/src/backend/commands/explain.c, (http://git.postgresql.org/gitweb/?p=postgresql.git;a=blob;f=src/backend/commands/explain.c;h=d99e5a86f0d5eaf61445affac52c1831d2e39c12;hb=refs/heads/REL9_4_STABLE#l846) Afaics, we're missing the following nodes: Insert Update Delete Foreign Scan Index Only Scan BitmapAnd BitmapOr Values Scan (shows up as a Seq Scan) LockRows I've recently made icons for DML, just for fun, so if no professional designer engages in, I could give it a try. Existing node icons are perfectly styled and have some ideas and logic put into them. I'm not sure I understand that fully. If there were some public discussions on existing node icons, please point them out! My thoughts on new icons: * DML: a pencil and a table with few blocks coloured (red=delete, orange=update, green=insert). Attached ex_update.png for example. Not sure about black crosses in the blocks. * Foreign Scan: like ex_cte_scan.png, but with "FDW" label on a table. * Index Only Scan: like ex_scan.png, but a binary-tree-like structure of blocks instead of a table. * BitmapAnd, BitmapOr: two lists of randomly chosen small "1"/"0", with "and"/"or" between the lists. * Values Scan: like ex_scan.png, but just several separate blocks instead of a table. * LockRows: like ex_update.png, but with a padlock instead of a pen. Please share your opinions and ideas. By the way, I couldn't find out, what a Seek node is and how to get it into a plan. -- Best regards, J.F.
