That was an unfortunate choice they made in having their second (int) 
argument be an OID. A quick fix would be to have it use the single (bigint) 
form of pg_try_advisory_lock. Something like this (untested):

diff --git a/bin/pg_repack.c b/bin/pg_repack.c
index af510ca..d638164 100644
- --- a/bin/pg_repack.c
+++ b/bin/pg_repack.c

    PGresult       *res = NULL;
    bool            ret = false;

+ const char     *params[1];

- -   params[0] = REPACK_LOCK_PREFIX_STR;
- -   params[1] = relid;
+ params[0] = relid;

- -   res = pgut_execute(conn, "SELECT pg_try_advisory_lock($1, $2)",
- -                      2, params);
+ res = pgut_execute(conn, "SELECT pg_try_advisory_lock($1)",
+                    1, params);

    if (PQresultStatus(res) != PGRES_TUPLES_OK) {
        elog(ERROR, "%s",  PQerrorMessage(connection));




You also may want to raise this as an official issue here:
