Description:

I noticed a bug in pgAdmin 1.22.0 (Jan 12 2016, rev: REL-1_22_0) running in
desktop mode on Ubuntu 16.04.

I'm not sure what causes the problem, but sometimes when I view all data in
a table, it shows the table without column names (these cells are simply
blank). I can fix the problem by restarting pgAdmin, so I don't think
anything is wrong with my code.

I think it may be related to using `Sequelize.sync({ force: true })`, but
I'm not sure and it seems there are many different ways to reproduce this.
For example, I found someone else experiencing this problem:
