In the opening the fight is to gain as much space as possible, control the center, and gain initiative for your pieces. As far as the pawn structures of each opening I would recommend a very good book on this by Andrew Soltis, Pawn Structure Chess. It explains the necessary traits of how each structure is created through typical setups, and how to play them.
Question about pawn structuresl
The lower the opponent the more ridiculous and complicated the pawn structure and hence position becomes. The plan isn't very clear.
As you increase you start to favour refined pawn structures that make a bit more sense, especially the pawn breaks.

Interesting article - thanks for sharing, Chris!
I have just started watching videos on pawn structures. It's fair to say I know very little about them. Just to give me an idea, would it be fair to say that once you know what your opening is going to be, you should know right away what the correct pawn structure is? Knowing that, should you plan to place your pawns on certain designated squares eventually? Thank you members.
No I don't think so.
This is a bit simplistic and maybe backwards.
The word opening isn't very precise. Many different pawn structures can result from the queens gambit declined, for example.
You can think in terms of the pawn structure typical of an opening, say an exchange variation of the queens gambit, in that opening and other positions where a similar structure arises.
But you 100% have to pay attention to what is on the board. Your position may well not be typical of the opening played.

@OP : I don't think there's any opening which always leads to the same pawn structure. However, some openings will often lead to a given pawn structure like QGD exchange as white, KID defence as Black, or French Rubinstein as Black.

Each opening as typical pawn structureS (for example the Caro-Kann has at least seven typical pawn structures, corresponding to the seven main lines (Panov, Exchange, Advance, Bishop, Solid, Larsen, Tartakower - there are of course many sidelines with different pawn structures, and each of the main lines can lead to different structures as well).
Each structure has typical plans and tactical motives (for examples the minority attack in the Exchange variation is a typical plan, and Qa5 check is a typical tactical pattern in almost every Caro-Kann structure).
You need to know the typical plans for each typical pawn structure for each opening you play, because overwhise you will be clueless about the strategic features of the position. (Note that different opening can have identic pawn structures, for example the IQP (isolated queen pawn) is a structure of the Tarrash and Semi-Tarrash in the Queen Gambit declined, and of the Panov attack in the Caro-Kann.

AngeloPardi- I like your post. Better than my own. It's not that my post is incorrect, but yours contains more useful information.
