Sure. Let's consider the below scenario, that I wanted to just verify the syntax
of documentations. For the autoconf/make build system, below commands can avoid
building C sources and generate needed .sgml files.
```
$ ./configure
...
$ cd doc/src/sgml/
$ make check
{ \
echo "<!ENTITY version \"19devel\">"; \
echo "<!ENTITY majorversion \"19\">"; \
} > version.sgml
'/usr/bin/perl' ./mk_feature_tables.pl YES
../../../src/backend/catalog/sql_feature_packages.txt
../../../src/backend/catalog/sql_features.txt > features-supported.sgml
'/usr/bin/perl' ./mk_feature_tables.pl NO
../../../src/backend/catalog/sql_feature_packages.txt
../../../src/backend/catalog/sql_features.txt > features-unsupported.sgml
'/usr/bin/perl' ./generate-errcodes-table.pl
../../../src/backend/utils/errcodes.txt > errcodes-table.sgml
'/usr/bin/perl' ./generate-keywords-table.pl . > keywords-table.sgml
'/usr/bin/perl' ./generate-targets-meson.pl targets-meson.txt
generate-targets-meson.pl > targets-meson.sgml
'/usr/bin/perl'
../../../src/backend/utils/activity/generate-wait_event_types.pl --docs
../../../src/backend/utils/activity/wait_event_names.txt
'/usr/bin/perl' ./sgml_syntax_check.pl --srcdir .
/usr/bin/xmllint --nonet --path . --path . --output postgres-full.xml --noent
--valid postgres.sgml
```
In case of meson build system, however, added test was run after all C files
were built. Ideally it is not needed.
```
$ meson setup ../postgres/
...
$ meson test --suite doc
ninja: Entering directory `/home/hayato/builddir'
[884/2468] Compiling C object ... // C
sources were built here
...
```
Also, I have been working on a project which translates the documentation [1],
and the syntax check is used for the github CI. I'm very sad if building
everything is needed to just check the doc.

I'm not faimilar with Meson, but my theory is that Meson cannot understand that
the test only depends on postgres_full_xml. That's why all sources are built.
Based on the discussion, the fix should be like;
```
--- a/doc/src/sgml/meson.build
+++ b/doc/src/sgml/meson.build
@@ -337,7 +337,8 @@ test(
'doc' / 'sgml_syntax_check',
meson_bin,

)
```
