Antonio Conte's side are now 11 points clear of closest challengers AS Roma after France midfielder Pogba scored with a powerful low drive in the 64th minute against a well-organised Bologna team who hardly ever left their own half.
Defeat for Bologna means they have dropped into the relegation zone, with Sassuolo's 1-0 win at Chievo Verona earlier on Saturday moving them level with Davide Ballardini's side on 28 points but above them on head-to-head results.
AS Roma secured second spot and a Champions League place by winning 1-0 at Fiorentina.
Roma's eighth win in succession was secured with a neat goal from Radja Nainngolan, who slid in to poke home Adem Llajic's through ball in the 26th minute of a tight game in Florence.
Rudi Garcia's side now have 82 points with four games to play, 14 ahead of Napoli who drew 1-1 at Udinese earlier on Saturday and 24 in front of fourth-placed Fiorentina.
But Roma's incredible recent form has not fazed reigning champions Juve who will travel to play them in Rome on May 9 as newly-crowned champions if they win their next two games at relegation-threatened Sassuolo and at home to Atalanta.
AC Milan boosted their chances of European football with their fifth straight victory as they thumped lowly Livorno 3-0.
While Inter Milan moved a step closer to qualifying for next season's Europa League with a 2-0 Serie A win over 10-man Parma.
Walter Mazzarri's Inter, who secured victory with second-half goals from Rolando and Fredy Guarin after Gabriel Paletta was sent off for the hosts, stay fifth but are on 56 points, five ahead of Parma and AC Milan.
Torino, two points further adrift in eighth, drew 3-3 with Lazio in an incredible match where Ciro Immobile scored his 20th goal of the season to give the away side a late lead only for Lazio's Antonio Candreva to equalise deep into stoppage time.
Third-place Napoli drew 1-1 at Udinese with Rafael Benitez's side taking a 39th-minute lead through Jose Callejon's superb volley but Bruno Fernandes slotted home an equaliser 10 minutes after the restart capitalising on a dreadful pass from Napoli keeper Pepe Reina.
