At least as far back as Inspector LEstrade in the Sherlock Holmes stories, mystery stories and novels about private detectives have usually featured a cop who was either
A complete dunce
A guy who provided helpful data to the detective, but couldn’t solve a case on his own if his life depended on it.
How many such cops can you name? Among those who come to mind:
Lestrade
Inspector Japp in the Hercule Poirot stories
Lionel T. Cramer in the Nero Wolfe stories
Lieutenant Quirk, in the Spenser novels

I don’t think Quirk counts as even remotely incompetent. On at least two occasions–Paper Doll and A Catskill Eagle–Quirk has to save Spenser from a mess he’s gotten himself into by working on his own; and in several other cases, Spenser complicates things by not being as forthcoming as he should; cf. Looking for Rachel Wallace, in which Quirk calls him on it.
Usually Quirk isn’t involved in Spenser’s cases directly; rather, someone gets murdered in the course of the novel and Quirk, being homicide commander, gets involved and permits Spenser to keep investigating the original case because Spenser may shake a clue loose, or Spenser comes to Quirk or Belson for information he, as a civilian, lacks official access to. When Quirk is directly involved in the case from the beginning, it’s usually because he’s using Spenser as a catspaw: in The Godwulf Manuscript, for instance, Quirk’s investigation is being interfered with by his superiors, so he feeds Spenser information to allow the him to do what politics prevent him from doing.
At other times, Quirk is acting as the supervisor of an investigative team in which he includes Spenser for political reasons. In Crimson Joy and Thin Air, Quirk brings Spenser in on the investigation for other reasons, but he is very clearly the person in charge (Spenser tacitly acknowledges it); Spenser simply happens to be the investigator on Quirk’s team whose assigned avenue bears fruit. It merely seems that Spenser is the best investigator in Quirk’s stable because we only hear about the cases Spenser is the key person in solving. If in Crimson Joy, for instance, the best avenue of investigation had been the one Belson was assigned, it would not have been a case Spenser would have told.

Lieutenant Walt Levinson and Sergeant Otis fit the bill in Richard Diamond, Private Detective. (The radio version.)
The Lieutenant mainly grumbles about how Diamond gives him ulcers and clutters up the town with bodies, and Sergeant Otis seems modeled on Lennie from Of Mice and Men, only surlier. He’s mainly there to give the protagonist someone to make cutting remarks to.
Lietenant Levinson is a little more sympathetic though, there’s a sense that he envies the lack of restraint that Diamond enjoys, and sometimes conspires with Diamond to give folks who run afoul of the law a break, if the circumstances seem to warrant it. He’s saved Diamond’s bacon a few times, but I don’t recall him ever contributing anything towards actually cracking a case.
Detectives Dundy and Polhaus in The Maltese Falcon. Too busy trying to pin thing on Sam Spade to actually deal with the facts of the case. One is complete thick (Dundy, I think), while the other gives Spade the benefit of the doubt.
Monsieur G----, Prefect of Police, in “The Purloined Letter,” predates Lestrade. Not very good at searching, is he?
Commissioner Gordon and Chief O’Hara in the Batman TV show. I doubt O’Hara could find the Joker if he were standing two feet in front of him.
It’s been awhile, but how good was Inspector Richard Queen in the Ellery Queen novels?
