I would use:
\(pg\. [0-9]+\)
This can be explained as
\( a ( symbol, has to be escaped as ( has meaning in regexp
pg the letters "pg"
\. a . symbol, has to be escpaed as . has meaning in regexp
space a space
[0-9]+ 1 or more occurences of a numerical digit
\) a ) symbol, has to be escaped as ) has meaning in regexp
