I have a 2008 Toyota Tacoma with 235,000 miles on it. It is in excellent condition and well maintained. Would it be prudent to replace the water pump before it shows signs of failure? I plan on keeping this vehicle forever.

Given age and mileage it might make sense but be sure to use an OEM pump from a trusted source. However you can really go down a rabbit hole with that approach - what about the alternator? Fuel pump? Power steering pump? Radiator? Hoses? There are a lot of parts that can fail on an old vehicle, many of which can leave you on the side of the road.

That thing is already 18 years old, so good luck. It could last quite a while yet (I drive vehicles much older) but be prepared to deal with age-related issues. Also be careful of severe frame rust that Tacomas of that vintage are prone to (assuming the frame has not already been replaced). If the frame rots out it's game over.
@chucktobias an alternator or hose can be changed by the side of the road . A timing belt driven water pump is a little more problematic.
I've had occasion to change out a water pump while on a trip but the type bolted to the outside of the engine and driven by a fan belt. Not fun, but doable. (Usually they'll give some warning before failing but in that case I stupidly did not check before hitting the road.)
Certainly if a vehicle uses a timing-belt driven water pump, at that kind of age and mileage the pump should be replaced and the timing belt as well.
Might be a good idea every oil change to keep an eye on your coolant reservoir for any unexplained drop in coolant as well as checking for any leaks. Other guys on here are much more experienced than me, but I think most water pumps show signs they need replacing before a 100% failure.
