libpq.so full name?

["surabhi.ahuja" <surabhi.ahuja@xxxxxxxxxxx>]

 hi

I had Postgres 8.0.0 installed on my m/c and

now i have installed Postgresql 8.1.4 (FC 4) x86 , 64 bit arch.

 

i rebuild my executable giving -L$(ROOT)/postgres/lib/ -lpq

 

the directory $(ROOT)/postgres/lib

contains libpq.so with size = 133320

 

it gives an error (linking error i think),

howver if i rename the above file to libpq.so.3 then it works fine.

What is this behaviour?

 

 

thanks,

regards
