pgsql: Don't initialize TLI variable to -1, as TimeLineID is unsigned.

Don't initialize TLI variable to -1, as TimeLineID is unsigned.

This was causing a compiler warning with Solaris compiler. Use 0 instead.
The variable is initialized just for the sake of tidyness  and/or debugging,
it's not used for anything before setting it to a real value.

Per report and suggestion from Peter Eisentraut.
