If all you need is to get the rest of the string after the last / you can just use some basic NSIS string handling:

Section

StrCpy $0 "jdbc:postgresql://localhost:5432/DatabaseName"
StrCpy $1 0
loop:
    IntOp $1 $1 - 1 ; Character offset, from end of string
    StrCpy $2 $0 1 $1 ; Read 1 character into $2, -$1 offset from end
    StrCmp $2 '/' found
    StrCmp $2 '' stop loop ; No more characters or try again
found:
    IntOp $1 $1 + 1 ; Don't include / in extracted string
stop:
StrCpy $2 $0 "" $1 ; We know the length, extract final string part
DetailPrint "|$2|"

SectionEnd

The WordFind function lets you do that, take a look at its examples

You should try the NSISpcre plugin, maybe you need some nasty regex :p
