Quick and dirty job to get some data into a DB wasted my entire evening.

Created table with few columns, tried writing to it from NodeJS app and it kept complaining I wasn't providing values for columns that didn't even exist. After ages pissing about decided that the DB gods had cursed this particular table so created a second one with same DDL. Now it worked first fucking time. Then it finally dawned on me, I'd managed to pick a reserved table name and the RDBMS didn't think to give me a warning when I created it. Not only did it not warn me but it kept going as it nothing was the matter and didn't report the extra columns on a SELECT *.
