Yes, to my built version.

I added in the start script of the server the following line about ldd,
to get it exactly in the LD_LIBRARY_PATH of the server:

...
case $1 in
  start)
        echo -n "Starting PostgreSQL: "
        test -e "$PG_OOM_ADJUST_FILE" && echo "$PG_MASTER_OOM_SCORE_ADJ" > "$PG_OOM_ADJUST_FILE"
        su - $PGUSER -c "$LD_ENV $DAEMON_ENV env > /tmp/pg_tde.ldd"
        su - $PGUSER -c "$LD_ENV $DAEMON_ENV ldd /usr/local/sisis-pap/pgsql-16.2/lib/pg_tde.so >> /tmp/pg_tde.ldd"
        su - $PGUSER -c "$LD_ENV $DAEMON_ENV $DAEMON -D '$PGDATA' >>$PGLOG 2>&1 &"
        echo "ok"
        ;;
...

After looking carefully at the file /tmp/pg_tde.ldd I saw the problem:

# egrep 'LD_LIBRARY_PATH|libcurl' /tmp/pg_tde.ldd
LD_LIBRARY_PATH=:/usr/local/sisis-pap/lib
        libcurl.so.4 => /usr/lib64/libcurl.so.4 (0x00007fc830146000)

LD_LIBRARY_PATH was set as it should to /usr/local/sisis-pap/lib but the 
libcurl.so.4 was not seen. I made curl by my own and this installed:

# ls -l /usr/local/sisis-pap/lib/libcurl*
-rw-r--r-- 1 bin bin 1315526 May  6 10:29 /usr/local/sisis-pap/lib/libcurl.a
-rwxr-xr-x 1 bin bin    1004 May  6 10:29 /usr/local/sisis-pap/lib/libcurl.la
-rwxr-xr-x 1 bin bin  735168 May  6 10:29 /usr/local/sisis-pap/lib/libcurl.so.4.8.0

but the pg_tde.so was loocking for libcurl.so.4 and not for libcurl.so.4.8.0

I made a symlink as

# ln -s /usr/local/sisis-pap/lib/libcurl.so.4.8.0 /usr/local/sisis-pap/lib/libcurl.so.4

and the server comes up fine:

# /etc/init.d/postgres162 start
Starting PostgreSQL: ok

# grep curl /tmp/pg_tde.ldd
        libcurl.so.4 => /usr/local/sisis-pap/lib/libcurl.so.4 (0x00007faefc8bd000)

I have to figure out why the making of 'curl' does not produce that
symlink by its own, or why the making of pg_tde.so let it ask for 
libcurl.so.4 and not for libcurl.so.4.8.0.

Thanks for your help, Adrian.
