Electronic – Best way to connect 2 pins that are next to each other
pcbpcb-design
The two pins are next to each other and they must be connect together.
How should I do that?
Just connect them together with a simple trace?
Or pour them together?

A large pour would allow more current (just like a wider trace), and would result in a larger solder blob. You probably need neither.
A simple trace between the middles of the pads might look like an accidental solder bridge if you don't know the circuit. To avoid such a misunderstanding, it might be a better idea to route the trace outside, if you can afford the space:
Yes, there is a strong RF current flowing through the capacitors of a crystal oscillator. In order to keep this current from coupling to/from free space (EMI considerations), it is necessary to keep the loop area of this circuit as small as possible.
In this case, the "loop" is the complete path through the crystal and the two capacitors. If you don't keep these components as close together as possible, the loop area will be larger than it needs to be.
