RE: AIX support

Hi Tristan,
Thank you for your feedback and suggestions.


As suggested, we have tried to implement a dependency-driven approach for static library builds, rather than using AIX platform tags.

    modified:   meson.build
        dep_static_lib = declare_dependency()                       << new dependency

        if host_system == 'aix'
            dep_static_lib = disabler()
        endif

    modified:   src/interfaces/ecpg/compatlib/meson.build
        ecpg_compat_st = static_library('libecpg_compat',
          ecpg_compat_sources,
          include_directories: ecpg_compat_inc,
          c_args: ecpg_compat_c_args,
          dependencies: [frontend_stlib_code, thread_dep, dep_static_lib],                       << new dependency
          link_with: [ecpglib_st, ecpg_pgtypes_st],
          kwargs: default_lib_args,
        )

    modified:   src/interfaces/ecpg/ecpglib/meson.build
        ecpglib_st = static_library('libecpg',
          ecpglib_sources,
          include_directories: ecpglib_inc,
          c_args: ecpglib_c_args,
          c_pch: pch_postgres_fe_h,
          dependencies: [frontend_stlib_code, thread_dep, libpq, dep_static_lib],                       << new dependency
          link_with: [ecpg_pgtypes_st],
          kwargs: default_lib_args,
        )

    modified:   src/interfaces/ecpg/pgtypeslib/meson.build
        ecpg_pgtypes_st = static_library('libpgtypes',
          ecpg_pgtypes_sources,
          include_directories: ecpg_pgtypes_inc,
          c_args: ecpg_pgtypes_c_args,
          c_pch: pch_postgres_fe_h,
          dependencies: [frontend_stlib_code, dep_static_lib],                       << new dependency
          kwargs: default_lib_args,
        )

    modified:   src/interfaces/libpq/meson.build
        libpq_st = static_library('libpq',
          libpq_sources,
          include_directories: [libpq_inc],
          c_args: libpq_c_args,
          c_pch: pch_postgres_fe_h,
          dependencies: [frontend_stlib_code, libpq_deps, dep_static_lib],                       << new dependency
          kwargs: default_lib_args,
        )

Also I would like to understand Peter/Heikki thoughts as well on this new implementation.

Thank you, Tristan, for your assistance. At present, the build appears stable

with the recent changes, however, the new dependency is causing impacts

elsewhere(with tmp_install). I will provide the consolidated patch after addressing these concerns.

Thanks,
Sriram.
