Thank you and sorry for the long delay! I tried the tag 5.6.0 (next time it will be the branch 5.6) with bullseye and `tlsa`, but I got the following error:
``` 0(1414) ERROR: <core> [core/sr_module.c:570]: load_module(): could not open module </home/gauss/lib64/gauss/modules/tlsa.so>: /home/gauss/lib64/gauss/modules/tlsa.so: undefined symbol: __dlclose 0(1414) CRITICAL: <core> [core/cfg.y:3787]: yyerror_at(): parse error in config file /home/gauss/etc/gauss.cfg, line 144, column 12-20: failed to load module ```
