Dear hackers,
While checking documentations, I found that one line notes our product as
"<productname>PostgreSQL</productname>", whereas another line notes as just
"PostgreSQL". For example, in bgworker.sgml:
```
PostgreSQL can be extended to run user-supplied code in separate processes.
...
These processes are attached to <productname>PostgreSQL</productname>'s
shared memory area and have the option to connect to databases internally; ...
```
It seems that <productname> tag is not used when the string is used as link or
title, but I cannot find other rule to use them. Could you please tell me discussions
or wikipage about it?
Best Regards,
