how to disable auto-completion

Hello<br /> Is it any option to disable auto-completion feature? If not, could it be added?<br /><br /> We bought SQL
Assistantwhich provides better functionality of this feature, unfortunately sometimes both solutions colide each
other.<br/><br /> BTW in pgAdmin manual is stated:<br /><i>You can optionally enable the Tab key to activate the
autocompletefeature as well - the can be done on the </i><i><a class="reference internal"
href="options-tab4.html#options-tab4"><em>[optionsdialog]</em></a></i><i>.</i><br /> Where <i><a class="reference
internal"href="options-tab4.html#options-tab4"><em>[options dialog]</em></a></i> is the link to Options description
includingscreenshot. But I found no the option here.<br /><br /> with regards<br /> MK<br />
